[Effect of gamma globulins against brain-specific non-histone chromosomal proteins on the reproduction of a conditioned response in grape snails].

The effects of gamma-globulins to brain specific nonhistone chromatin proteins (BSNCP-3.5;-3.6) on conditioned food avoidance behaviour (carrot or apple) was studied in the garden snail. It was found that half an hour later the intracorporeal injection of BSNCP-3.5 inhibited conditioned carrot, but not apple avoidance reaction. Injection of BSNCP-3.6 was ineffective in avoidance behaviour induced by both conditioned stimuli. BSNCP-3.5 is suggested to be specifically involved in the process of information recollection.
