Ivan Andreevich Bulygin (10.02.1907, v. Radushkovo, Pochinok District, Smolensk Region, Russia – 12.04.1984), physiologist. Academician of the National Academy of Sciences of Belarus (1959; Corresponding Member since 1956), Doctor of Biological Sciences (1952), Professor (1954). Honored Scientist of the BSSR (1967). Member of the Great Patriotic War.
Work on the physiology of the autonomic nervous system and cortico-visceral relationships. He created a new direction in the study of the afferent link of the vegetative nervous structure and the structural and functional organization of the vegetative ganglia. Established the presence of conditioned-reflex effects of the cerebral cortex on the motility of the stomach and intestines and found patterns of interoceptive effects on the reflex activity of the spinal cord and brain. He advanced and experimentally substantiated the statement about the complex functional structure of the integral interoceptive reaction of the organism, derived and formulated the concept of a plurality of afferent pathways of interoceptive reflexes and their complication in phylogenesis, the chain and ring neurohumoral mechanisms of visceral reactions. Developed new principles of the structural-functional organization of the vegetative ganglia, put forward and substantiated the general position on the relationship between divergence and convergence in the activity of the nervous system.
Published over 220 scientific papers, incl. 12 monographs.
State Prize of the USSR (1978) for the series of works "New principles for the organization of vegetative ganglia". State Prize of the BSSR (1972) for the monographs "Studies of the laws and mechanisms of interoceptive reflexes" (1959), "Afferent paths of interoceptive reflexes" (1966), "Chain and ring neurohumoral mechanisms of visceral reflex reactions" (1970).
Awarded with the Order of Lenin (1977), the Red Banner (1944), the Red Banner of Labor (1971), the Red Star (1943), and medals.
