FESSAR Alfred (Fessard Alfred, 1900 — 1982) is the French neurophysiologist, the member of the French Academy of Sciences and National medical academy.
Ended in 1925 f-t of physics and physiology Parisian un-that (Sorbonne). Worked in Pyeron's laboratory (H. Pie-ron) in the College de Frans, in 1936 protected dokt. thesis. From 1943 to 1949 the director of laboratory; from 1949 to 1972 professor of general physiology in the College de Frans and at the same time the director of the center of physiological researches of a nervous system organized by it in 1949; was also the director of the National center of scientific research (1947 — 1972).
The main researches of A. Fessa-r are devoted to problems of an electrophysiology of a cell, mechanisms of activity of a brain. It possesses a merit of implementation of electrophysiologic methods in practice scientific and a wedge, researches in France; the possibility of an uslovnoreflektorny depression of an a-rhythm of EEG was opened for them; fundamental works on physiology of electric bodies of fishes are performed. A. Fessar and his employees among the first carried out intracellular recording of activity of neurons; proved that touch information extends in a brain much more widely, than it was possible to conclude from the evoked potentials given to registration; compared behavior of animals with changes of the bioelectric activity of a brain registered by means of chronically implanted electrodes.
And. Fessar was the honorary member of academies and the countries, scientific about-in a row, one of founders of the International organization for studying of a brain (IBRO), the member of executive committee and central office of IBRO, the secretary general of Association of physiologists (1968 — 1972).
