By averaged summary activity of symmetric points of the cat auditory cortex and amygdala evoked by sound, the character of interaction (Spirman coefficient of correlation) was determined between the structures before, at elaboration, at extinction and restoration of instrumental food-procuring reflex and also at automatization of the reflex. Individual character of co-tuning of the cortex and amygdala was found at adaptation of the animal, changing into close interconnections at formation of the reflex and into disturbance of their correlation at its extinction. Stabilization of the reflex up to the stage of automatization was accompanied by the weakening of connections between the cortex and amygdala. The results testify to complex and dynamic character of interaction in the system cortex-amygdala in conditioned activity.
