George Mchedlishvili, Professor in microcirculation and cerebral blood flow, the world renowned, distinguished Georgian scientist, was born on 16th June, 1921 in Tbilisi. In 1944 he graduated from the Tbilisi State Medical Institute and then, post-graduate courses of the same Institute (1947) with speciality of a pathophysiologist. G.Mchedlishvili defended candidate’s dissertation in 1947 in Tbilisi under supervision of V.Voronin, an honorary academician of Georgian Academy of Sciences, and doctoral dissertation in 1957 in Moscow.
Being still a student in 1942 he began scientific activity in the field of normal and pathological physiology at Ivane Beritashvili Institute of Physiology of the Georgian Academy of sciences, where he has worked till the lees of his life and was head of scientific subdivisions: Department of Pathophysiology (till 1963) and then, Laboratory of Blood Circulation.
The major realm of G.Mchedlishvili’s scientific activity was invariably normal and pathological physiology of microcirculation and peripheral blood flow (mainly in the brain). His scientific production within 1946-2004 compasses about 700 publications, including 7 monographs, of which 2 were published in Leningrad and 2 – in New-York. He edited: 13 scientific books (among them 8 in English), more than 370 scientific papers (among them 130 in English), 25 articles were included into the Encyclopedia, 4 scientific-popular books and more than 300 theses of reports.
Two physiological phenomena for the first time in the world described by G.Mchedlishvili were recognized and registered by the Soviet State expertise as a discovery. These are: Principles of erythrocytes distribution in the human and animal blood circulation system (1954) and Regulation of cerebral circulation by magistral and pial arteries (1959). Many scientific personnel trained under guidance of George Mchedlishvili are successfully working not only in Georgia, but also abroad - in Poland, Sweden, Germany and America.
In 1963-1990 George Mchrdlishvili established and held 7 International Symposia (known the world over as the Tbilisi Symposia) whereat the leading scientists in the world considered the live problems of microcirculation and cerebral blood flow.

Alexander Bakuradze was born on December 11, 1905 in Georgia, in the village Rekha of Tsalka district. In 1924 he finished a secondary school in Tbilisi and in the same year became a student of Medical Faculty of Tbilisi State University, after graduation of which in 1930 he was invited as an assistant to the Normal Physiology Chair of the newly founded Tbilisi State Medical Institute. In 1938 he was elected as a reader at the Chair, while from 1945 to 1985 was a Head of the Chair.
In 1933 Alexander Bakuradze by Ivane Beritashvili’s invitation started working in biology sector of Georgian Department of Transcaucasian branch of the SSR Academy of Sciences. In 1934-35 he in Leningrad and Moscow was acquiring new methods and he himself conducted research in I.Pavlov’s, E.London’s and I.Rasenkov’s Laboratories. Having returned to his motherland, he until 1951 continued to pursue scientific activity at the Institute of Physiology.
In 1951, A.Bakuradze was appointed as a Head of Pathologic Physiology Laboratory at the Institute of Spa Treatment of Georgia Health Care Ministry. In 1966 he once again was invited to I.Beritashvili Institute of Physiology where he formed a laboratory studying primate’s behavior.

Research interest was developing in three direction: physiology of visceral systems, neurophysiology and neuropsychology, experimental spa treatment and physiotherapy.
A.Bakuradze, together with Ivane Beritashvili, authored fundamental investigations in the spinal cord physiology, followed by the discovery of antidromic inhibition phenomenon and inhibitory neurons (1940).
A.Bakuradze was among the pioneers to apply electrographic recording of the spinal cord biopotentials and showed that general inhibition of the spinal cord is mediated via substantia gelatinosa of Rolando/ Together with his associates, he was the first in Georgia to deal with the problems of individual brain structures in mnemonic processes, in particular the role of the prefrontal cortex. A.Bakuradze’s contributions to the development of the alimentary system physiology, to the studies of neurohumoral mechanisms of hunger and satiation, are commonly recognized.
A.Bakuradze’s works in the field of experimental resort-cure and physiotherapy are concerned with the effects of physical and climatic factors on the work of alimentary tract, cardiovascular system, course of experimental arthritis, recovery of the peripheral nervous system and on healing of wounds.
In 1941-1945, during the Second World War, A.Bakuradze worked in evacuation hospitals where he conducted EEG investigations in warriors suffering from contusion and epilepsy.
A.Bakuradze with I.Beritashvili together with other scientists have experimentally studied the effect of explosion wave on different systems of the organism and worked out prevention ways from resulting injuries.
Great is A.Bakuradze’s desert in bringing up many generations of physicians and initiation of a large scientific school. He was the author of about 300 works including 4 monographs. Under his supervision 27 doctoral and more than 92 candidate dissertations were defended in medicine.
He was a member of International Brain Research Organisation (IBRO), many times was elected on the board of I.Beritashvili Physiological Society (as scientific secretary, vice-president or President), was a member of the presidium of I.Pavlov All-Union Physiological Society; he supervised the physiology panel of Georgian Encyclopedia, was on the editorial board of a number of scientific journals.
A.Bakuradze participated in many scientific forums, was organizer of several conferences on alimentary physiology, experimental spa treatment and physiotherapy. His contributions to the Georgian scientific school and medical education was acknowledged by I.Tarkhnishvili Prize and many state rewards. His scientific legacy will for a long time be a guideline for researchers in the field of Georgian natural science and medicine.

The founder in Georgia of scientific direction and laboratory of pain and analgesy physiology, doctor of biological sciences, Professor Saurmag Butkhuzi was born on 22nd July, 1927. His parents were Michael Butkhuzi and Nina Chachanidze. Father was physician-surgeon working in different towns of Georgia in the 30s of the last century, during the World War I he was a leading surgeon and a chief physician of the Eastern Front 10th division. Further on he served as a leading surgeon of the USSR Baltic Front, was decorated with two Red Star Orders.
Saurmag Butkhuzi graduated with honors the stomatologic faculty of the Tbilisi State Medical Institute in 1949 and in 1940-53 worked as a maxilla-facial surgeon at the same Chair of Tbilisi Medical Institute where he served as an intern and where he has modified some stomatologic methods, having received discovery certificates. In 1953-56 he was a post-graduate student at the Institute of Physiology of the Georgian Academy of Sciences and under leadership of academician Ivane Beritashvili he defended the candidate’s dissertation in the nerve-muscle physiology the opponent of which was invited from Leningrad a well-known specialist – Professor Elgraph Zhukov, who had highly estimated the theses and even published in his monograph a fragment from the dissertation. In 1969 S.Butkhusi defended a doctoral dissertation on the function of the caudate nucleus. In 1956-61 he worked at he Institute of Physiology first as a junior and in 1961-76 as a senior scientist. In 1976-2005 he headed the Laboratory of Pain and Analgesy Neurophysiology launched by himself. He authored over 150 scientific papers published in local and International physiological journals, was receiver of Tarkhnishvili prize for his monograph. He was first among the former Soviet physiologists to pursue a systemic study of the brain basal nuclei functions, he physiological bases of the cortical and subcortical nuclei relationship with the reticular formation. Saurmag was among the first Soviet scientists studying for some years the structure of the caudate nucleus, its physiology, its relationship with the cerebral hemispheres. S.Butkhuzi refuted the then dominated point of view of the basal nuclei having only motor function and demonstrated that these formations, alongside with being involved in the extrapyramidal motor reactions coordination, plays a pivotal role in the brain integrative activity. He was one of the first to express a contention on the established relationships of the caudate nucleus and the substanyia nigra, their participation in Parkinson disease, this being corroborated later on by both physiologists and neurologists. A significant realm of Saurmag’s scientific activity was to study the physiological mechanisms subserving pain, its inhibition and analgesy.
In 1971 he formed a team studying the pain mechanisms and since 1976 led the laboratory of pain neurophysiology which was the first within the former Soviet Union. In 1971-76 at the Institute of Physiology of Czechoslovak Academy together with check colleagues he pursued joint work on nociceptive afferentation of pain receiving cortical area in the trigeminal nerve system, as well as the corpora quadrigemina pain afferentation transmitting pathways to the higher levels of the CNS. He has established that the existence of brain stem pain inhibiting pathways causes pain inhibition without analgetic drugs. Also, he has made significant contributions to the functional organization of the main pain inhibitory stem cells of the central grey matter. These findings were published in the International journal Brain Research for 1972, 41, 211-213; 1974, 66, 325-327. Saurmag Butkhuzi was the first to characterize the neurophysiological activity this structure as a major link of the analgesic endogenous system. He was also first worldwide to develop the so-called “pain causing tooth method”. He had first implemented that methodology during his collaboration with Professor Vycklicky at the time of his scientific mission to Czechoslovakia. The method is now referred to as Butkhusi-Vycklicky method. In 1971 Saurmag Butkhuzi took acupuncture studying courses held in Alma-Ata, He was one of the first specialists in the field of acupuncture and reflexotherapy. Since 1980 he had worked in the laboratory founded by himself studying the functional organization of the brainstem analgesic structures implicated in pain and analgesy integration. He had studied neuronal activity of gray matter, cerebellar nuclei and trigeminal nerve, and the changes occurring in them by the impact of narcotic analgesic substances; pursued a detailed study of the hypothalamic and central gray matter antinociceptive system interaction. This was a new word said in relation to pain and analgesy. In 1975 S,Butkhuzi was elected a member of the International Brain Research Organisation (IBRO). Since 1990 he had been a member of pain studying international association (IASP), had been included in the 1996 XVII edition by the bibliographic Center of journal “Who is Who” – an advanced figure”, supervised 8 candidates and 2 doctoral dissertations. S.Butkhuzi in 2002 was decorated with the Order of Merit.
Saurmag Butkhusi died on November 6th, 2010.
Dimitry Gedevanishvili was born on September 15, 1902, in Tbilisi.
After secondary school education he, in 1920, matriculated in Tbilisi State University, having graduated its Medical Faculty in 1927. In the same year he started working in a clinic of Neuropathology under guidance of Professor Simon Kipshidze, and then in a physiological laboratorie and chair of Tbilisi State University which was directed by the renowned Georgian physiologist Ivane Beritashvili. In 1937 D.Gedevanishvili was conferred on the degree of a doctor in biological sciences, and later, the title of a professor. He headed physiological chairs at Pharmaceutical and Stomatological Institutes. In 1946 D.Gedevanishvili was elected a corresponding-member of Georgian Academy of Sciences. In 1959-1973 he was a pro-rector in scientific affairs of the Tbilisi Medical Institute.
For more than a quarter of century D.Gedevanishvili has been studying Georgian medicinal flora, making its biological standardization. His works done in this area have tangibly contributed to the cause of study of Georgian natural chemical compounds. Great erudition and ability for deep analysis enabled him to solve in an original way quite a number of priority problems, in result receiving international recognition.
D.Gedevanishvili is the author of over 200 scientific works. The proof of his competent authority and broad recognition is also the fact that he was one of the editors of international scientific journal “Biomedical Computerization”, a member of world-wide Organization for Cybernetics and General Systems’ Management and International Association for Cybernetics.
He was Honored Scientist of Georgia, was decorated with Orders of Lenin, of the Red Banner of Labor and of Honor, and some medals.
Dimitry Gedevanishvili died on March 28, 1990 in Tbilisi. He is buried in the Didube Pantheon of Writers and Public Men.
George S.Vatsadze was born in 1883 in Tbilisi.
In 1911 he finished with highest honor the Tbilisi 2nd high school for boys, left for Moscow to continue studying at the Moscow Medical University. During World War I G.Vatsadze being a freshman volunteered in the “Red Cross” detachment. In 1915 in Petersburg at the Emperor’s Palace the queen Mariam was awarding a group of officers, among them was George Vatsadze too. After graduation from the Medical Institute he worked in Russia, but because of farther’s illness had to return to Tbilisi.
The then Tbilisi governor appointed him a general practitioner in the village Digomi. Soon afterwards I.Beritashvili, just being returned from Russia, invites him to work at the Chair of Physiology of Tbilisi University Medical Faculty.
G.Vatsadze’s activity at that period was not restricted with scientific research only. In 1921 he was head of health care department of workers’ deputy executive council. And later, served as a vice-commissary of health care and head of Resort Management, at different resorts of Georgia he initiated Summer Convalescence Camps for children, sanatoria for infants. G.Vatsadze focused attention on the resorts Borjomi, Abastumani, Utsera, specially studied the effect of mineral waters on human body, particularly of Borjomi water. For this reason he explored the effect of Borjomi on digestive and metabolic processes.
In 1926 G.Vatsadze left for Germany for a couple of years to Kili Institute of Physiology. The years spent there proved extremely fruitful for him as a scientist. On returning to his fatherland with doctor’s degree, he again continued to work with I.Beritashvili.
In 1930 when the Medical Faculty was to be separated from University as a separate Institute, Ivane Javakhishvili recommended G.Vatsadze in the capacity of rector of Medical Institute. Thus he becametyhe first rector (1930-1936) of Tbilisi State Medical Institute. On his initiative and guidance two buildings and a hostel for 360 students have been erected.
In 1944 G.Vatsadze was granted the title of honored scientist. In parallel to his recognition started his Golgotha, lasting for 12 years.
In 1945 professor G.Vatsadze was arrested and confined in a cellar of Ministry of Domestic Affairs. In a few months he was sentenced a 10-year imprisonment. Fortunately, his family escaped repressions. In 1949 G.Vatsadze was sent into exile to Spasski penitentiary nearby Karaganda. He was rehabilitated only in 1958.
George Vatsadze died in 1971 in Tbilisi.
Vladimir Voronin was born in 1870 in Russia, village Nikolskoe of Tula province.
Since 1893, after having graduated from the Medical Faculty of Moscow University, V.Voronin worked in Germany, then in France at Pasteur Institute in Paris. His scientific works of that time are as important now as ever.
In 1897 he defended doctoral dissertation. In 1908 a title of Professor was conferred on him. From 1908 to 1922 he was head of General Pathology and Bacteriology Chair at Odessa University, at the same, of Odessa Bacteriological Station.
In 1922, the founders of the newly launched Tbilisi State University invited him to be Chief of Pathophysiology Chair at Medical Faculty of the University. He headed this Chair also after disintegration of the Medical Institute as a separate educational Institute (from 1930 to 1955). At the same time he, since 1944, headed the Pathophysiology Department at Ivane Beritashvili Institute of Physiology of Georgian Academy of Sciences and the Pathophysiology and Morphology Department at the Academy. A distinguished scientist (since 1941), an honorary member of Georgian Academy of Sciences (since 1944) V.Voronin had gone a long way in science. The scope of his scientific interests was the study of general pathology of inflammation, blood circulation and the peripheral nervous system. He was distinguished by his fundamental and encyclopedic knowledge in the fields of physics, chemistry, mathematics, he had phenomenal memory, was a highly experienced researcher and teacher. All this found its reflection in his two-volume “Handbook of Pathophysiology” (1947-1948). These books are important by their content and originality, since for tackling and solution of questions concerned with pathogenesis of multiple diseases V.Voronin applied the laws of physics, mechanics and mathematics. About 70 of his published works dealt with the questions of pathophysiology, as well as application in medicine of statistics and cybernetics.
Great is V.Voronin’s contribution to the preparation of highly qualified scientific personnel. Among his pupils were not only well-known pathophysiologists (A.Bogomolets, I.Zaalishvili, G.Mchedlishvili and others), but also many clinicians (P.Gertsen, V.Filatov, M.Yasinovski, L.Dmitrienko, K.Eristavi, I.Lortkipanidze, A.Cheishvili and others).
From 1955 to 1976 the Head of Pathophysiology Chair at Tbilisi State University was his pupil, Professor Irene Zaalishvili; from 1976 to 1990 the Head of the Chair was also his pupil, Professor Teimuraz Natadze. V.Voronon’s scientific traditions were continued by Professor Vakhtang Kipiani, who was the Head of the Chair (now Department) from 1990 to 2015.
V.Voronin has never been a member of the Communist Party, notwithstanding, he was awarded with two Orders of Lenin and two Orders of Red Banner. In 1949, V.Voronin was awarded with A.Bogomolets Scientific Prize by Ukraine Academy of Sciences.
To the lees of his life V.Voronin did not leave Georgia, which he was fond of and almost 40 years he spent for flourishing science in Georgia.
V.Voronin died in 1960 in Tbilisi.
Scientific activity of a distinguished Georgian neuromorphologist, Professor Archil Mikeladze, MD was closely associated with I.Beritashvili Institute of Physiology of the Georgian Academy of Sciences. As back as in the 1950s on the initiative of Ivane Beritashvili a group of neuromorphologists was formed, which since 1960 was led by A.Mikeladze who gathered together gifted young people – Gulnara Kiknadze, Eleonora Dzamoeva, Inga Kakabadze, Mzia Zhvania, Anna Tsitsishvili, Helen Mkheidze, Ilia Lazrishvili. The team pursued studies under A.Mikeladze of neuronal organization and monosynaptic connections of the CNS various areas. It has been established in that period that the frontal lobes of the cerebral hemispheres, namely the proreal gyrus, has afferent and efferent monosynaptic connections both to different cortical regions and subcortical structures.
In 1964 by I.Beritashvili’s endeavor the Institute purchased a Japanese electron microscope for A.Mikeladze’s team. From this period practically for the first time in Georgia systematic exploration of fine structure of biological systems, viz. of the nervous system has begun. At the beginning of the 60s of the last century known were the peculiarities of ultrastructural organization in the CNS individual areas, the types of neurons and glial cells were not identified, the existence of different type synaptic and monosynaptic specialized contacts was not known. Therefore, at the initial stage of scientific activity the team studied the ultrastructure of neurons, synapses and neuroglia under normal conditions and this set groundwork for working out identification criteria of the mentioned structural elements.
The findings yielded just in a few years acquired the all-union recognition and A.Mikeladze was elected as a member of the Electron Microscope Scientific Council at the Soviet Academy of Sciences and a chairman of Georgian section of the council. The Electron Microscopy Laboratory of the Institute of Physiology (that has been the name of the group since 1967) constituted a base of the Council and just in this Laboratory qualified specialists in the field of electron microscopy were prepared under supervision of A.Mikeladze for the scientific institutions not only of Georgia, but also of other republics.
Great are Prof. Mikeladze’s desert in the organization of the Electron Microscope International School and Exhibition in Tbilisi in 1969 and 1971 that had given impetus to wide extension of research in Georgia in this direction. Under his supervision, the ultrastructure of functionally divergent areas different type neurons, interneuronal synaptic and nonsynaptic connections, neuroglial cells and vascular capillaries was studied in norm and under modeling of different pathological processes. He together with his associates has demonstrated that as distinct from the projection neurons within the subcortical structures, whose most part of perikaryon’s surface is covered with presynaptic terminals in pyramidal neurons of any neocortical zone the majority of synapses are localized on thin dendritic offshoots and spines.
In A.Mikeladze’s scientific activities the issues of glial cells and neuron-glia interrelationship were of pivotal importance. It was been established that in the process lysis of degenerated nerve fibers together with macrophages-microgliocytes, the astrocytes are also involved.
Studied by A.Mikeladze and his associates was the structure of neurons, glial cells and capillary network of the vegetative nervous system’s central nuclei on the level of light and electron microscopy. The evidence obtained was generalized in his monograph published in 1968 entitled: “The Structural Organization of the Central Nervous System Vegetative Nuclei”. In recognition of A.Mikeladze’s achievements in the field of electron microscopy, he was elected as a chairman of International Conference on Electron Microscopy, held in 1973 in Tbilisi.
A.Mikeladze and his associates actively collaborated with the Institute’s physiological laboratories and conducted joint research with the Laboratories: GeneralPhysiology of the Cortex (head, Prof. Alexander Roitbak), the Brain Blood Circulation (head, Prof.George Mchedlishvili), Biochemistry (head, Acad. Peter Kometiani), Neurobiology of the Sleep-Wakefulness Cycle (head, Prof. Tengiz Oniani).
He was the author of multiple papers and a participant of a number of International forums in the field of electron microscopy.
Some publications by A.Mikeladze:
Monograph - «The Structural Organization of the CNS Vegetative Nuclei». «Metsniereba», Tbilisi, 1968 (in Russian).
Elguja Moniava was born on February 11, 1927 in the village Khuntsi of Martvili region.
In 1951 E.Moniava graduated from the State Medical Institute of Tbilisi. In 1951-1953 he worked in the Center of Medicinal Physical Culture of the Georgian Ministry of Health Care. In 1954-1957 he was a postgraduate student at the Institute of Physiology of the Georgian Academy of Sciences. From 1957 till 1964 he worked at this Institute as a junior researcher, while from 1964 till 1977 as a senior researcher.
In 1975 E.Moniava defended a doctoral dissertation and earned the degree of MD. In 1977 he was awarded the title of a Professor.
The scientific activity E.Moniava started at the Institute of Physiology with experiments on frogs and cats. He was an excellent experimenter and was distinguished by many noteworthy features. For stimulation of different spinal areas he used the microelectrodes made by himself, for this he deserved praise even from the great scientist of Georgia Ivane Beritashvili. His further scientific research was associated with the laboratory of famous person and scientist Sergi Narikashvili. For 20 years E.Moniava has been dealing with the problems of the brain reticular formation and has made many important contributions to this problem.
In 1977 on the base of I.Beritashvili Institute of Physiology E.Moniava set groundwork to founding a laboratory of quite a new direction – neuroendocrinology, of which he has been head for about 30 years. He succeeded in a short span of time in attracting scientific personnel and postgraduate students and involved them in active work. It is just in this laboratory that a number of facts of important scientific priorities were revealed. The role of hypothalamo-hypophysial hormones under the action of small doses of vasopressin and oxitocin on electrical activity of the cerebral cortex and the possible mechanisms subserving these effects have been demonstrated.
Important findings have been achieved in behavioral studies. The involvement of vasopressin was shown in memory mechanisms and also in formation of conditioned reflex reactions in early phases.
Just in the Laboratory of Neuroendocrinology in multiple explorations were demonstrated clear-cut properties indicating participation of the hypothalamo-hypophysial neurohormones in basic process of the CNS.
E.Moniava was a known specialist in the field of neurophysiology and neuroendocrinology not only in Georgia, but also abroad, he authored about 200 scientific papers and several monographs.
In 1980 he was elected as a member of the International Brain Research Organization (IBRO). And in 1996 a member of the Georgian Academy of Ecological Sciences and of the New-York Academy.
In 1990 for a cycle of works “The Thalamo-cortical Relationship”, together with Professor Sergi Narikashvili, he was awarded Ivane Beritashvili prize.
In 2000 E.Moniava was granted Honor’s Order, and in 2002 a Medal for Loyalty to Tbilisi. By his supervision 15 doctoral and candidate dissertations were defended.
Professor Vakhtang Mosidze was born on September 20th, 1926 in Tbilisi. In 1944 he finished with honors the Tbilisi secondary school N1. In 1944-49 was a student of the Tbilisi State Medical Institute. In 1949-52 was an intern at the Institute’s hospital department. In 1952 he successfully passed exams in physiology to the commission chaired by Ivane Beritashvili and was sent to Leningrad to take postgraduate courses at the Institute of Experimental Medicine in the Department of Physiology, under supervision of Prof. K.Abuladze, corresponding-member of the USSR Academy. In 1955 he defended thesis on “Conditioned and Unconditioned reflexes following transection of the corpus colliculus”. In the same year he began working at Ivane Beritashvili Institute of Physiology first as a junior and then a senior scientific researcher. In 1962 he defended doctoral thesis at the scientific council of the Tbilisi Medical Institute on: Coupled and separated work of the brain. In 1965 Prof. V.Mosidze was appointed as a Head of laboratory of Conditioned Reflexes (Laboratory of Interhemispheric Interrelationship since 1972). He was a chairman of the brain interhemispheric interrelationship commission at the Georgian Academy of Sciences, was a member of IBRO and since 1972, of the European Organizations for brain and behavior studies. In 1974 he became an honored scientist of Georgia, while in 1976 was awarded I.Tarkhnishvili Prize. In 1988 Professor V.Mosidze was elected as a corresponding member of the Georgian Academy of Sciences. He was also a member of the New-York Academy. In 1991 he was nominated and elected as director of the Institute of Physiology. In 1994 for his contributions together with his associates to the problem of the brain symmetry and asymmetry he was awarded the State Prize, later on, was elected as an honorary citizen of Tbilisi. He died on February 26th, 1999.
V.Mosidze’s works are mainly devoted to one of the extremely important problems of the present-day neurology, i.e. the brain interhemispheric relations. His findings shed light not only on the role of interhemispheric exchange of sensory inputs, but also on the involvement of stem cells in the hemispheric relations and on the importance of these processes for conditioned reflexes and memory. Clarified was the importance of the corpus colliculus for synchronous activity of the cerebral hemispheres and for interhemispheric generalization of strychnine discharges. Study was pursued of callosal neurons’ characteristics, their target neurons and a contention is expressed that via these neurons must be realized the horizontal transcommissural relations of hemispheres that is required for the brain integrative activity. The neurophysiological mechanisms for imprinting were clarified. The problem of functional asymmetry and specialization has been addressed.
V.Mosidze was the author of about 200 publications including 6 monographs. It is worthnoting that his findings have not only theoretical, but also practical importance for neurological clinicians, physiologists, psychiatrists and neurolinguists.

Having returned to Georgia, he continued active research work and formed new scientific units. In 1977 he headed laboratory of Nerve Cell Physiology, Pathology and Pharmacology, organized by him at the Institute of Physiology. In 1983 he founded and headed Neurobiological laboratory at the Tbilisi State University, where he developed quite a new direction translational medicine involving therapeutic monitoring of drugs and pharmacokinetic.
V.Okujava was an excellent organizer of science. This feature of his activity manifests itself since the 70s. In 1973-75 he is prorector at the Tbilisi State Medical Institute for scientific affairs, while in 1975-80 was an academician-secretary in the Department of Physiology and Experimental Medicine of the Academy.
Since 1980 a new stage in his life begins when he is appointed as a rector of the Tbilisi State University and works in this capacity till 1985.
It is in this period that his capabilities as an organizer get quite imminent. He devotes his efforts and energy to the development of science at the University. He takes an active part to initiate new and extend the existing research laboratories both in natural science and social disciplines.
V.Okujava was a member of different scientific institutions and societies: President of I.Beritashvili Physiological Society (1975-2011), chairman of Advisory Board at the Tbilisi State University, a member of the Presidium of the Georgian Academy of Sciences, a member of All-Union Scientific Council of Nervous System Physiology and Pathology, a member of International commission of epilepsy, International Brain Research Organization (IBRO) and a representative of national committee, etc, he was on the editorial board of a number of foreign scientific journals: Electroencephalography and Clinical Neurophysiology, Neurophysiology, Epilepsy Research, a member of editorial collegiums of the Bulletin of Georgian Academy of Sciences, Editor-in-chief of Proceedings of the Georgian Academy of Sciences, Biol. Series. V.Okujava is the author of 326 scientific works, among them 6 monographs. He supervised 31 theses, including 5 doctoral ones. In sundry times he was awarded by Ivane Beritashvili Prize and Horesm International Prize.
To the less of his life V.Okujava pursued rather fruitful scientific activity, was director of many international and local Scientific Projects.
The major realm of his interests were: modeling of neurological disorders and study of their neurophysiological mechanisms; study of neurophysiological bases of epilepsy; clinical electrophysiology; experimental and clinical neuropharmacology; investigation of memory neurobiological mechanisms on the neuronal level; behavioral researches – forms of memory and problems of their disorders, modeling of psychopathologic phenomena, etc.
Georgian physiologist, scientist of merit of the Georgian Academy of Sciences, professor, corresponding member and member of the Scientific Council of the former Academy of Sciences of the Soviet Union (now the Russian Academy of Sciences) Alexander Roitbak was born on February 17, 1919 in Odessa, Ukraine. In 1941 he graduated from the Kiev Medical Institute. Since 1944 he pursued scientific activity in the Institute of Physiology of Georgian Academy of Sciences. A.Roitbak was known as a pupil and follower of famous Georgian physiologist Ivane Beritashvili. Since 1960 he has been head of Laboratory of General Physiology of the Cerebral Cortex. In 1968 A.Roitbak was elected a corresponding member of the USSR Academy of Sciences.
His major contributions dealt with the questions of neurophysiology and electrophysiology of the nervous system. He has studied direct responses of the cerebral cortex and substantiated a postsynaptic nature of dendritic potentials. He discovered that at cortical rhythmical stimulation in the cortex may arise a focus of excitation – “dominant”. He has established that human reaction time is associated with breathing phases and proved participation of neuroglia in origination of prolonged electric potentials in the cerebral cortex. A.Roitbak is the author of hypothesis on a role of neuroglia in temporary connections as the basis of conditioned reflexes. His unique investigations in brain physiology have been recognized by the worldwide scientific community.
Since 1960 A.Roitbak has been a member of International Brain Research Organization (IBRO), was decorated with “Order of Honor”.
A.Roitbak died on December 24, 1991 in Tbilisi.
