Ivane Beritashvili: founder of physiology and neuroscience in Georgia.

This paper is dedicated to one of the outstanding scientists of the twentieth century--Ivane Beritashvili. He was a Georgian physiologist who graduated from St. Petersburg University and worked under the supervision of N. Wedensky. He founded the Department of Physiology and the Institute of Physiology at the University of Tbilisi, Georgia. Among his numerous contributions was the discovery of the rhythmical course of reciprocal inhibition in spinal reflexes, the first demonstration of the excitatory and inhibitory reactions in the brain stem neuropil. But Beritashvili's most significant contribution was the discovery of the mediation of animal psychoneural behavior by image-driven memory.
