[Effect of stimulation of the acetylcholinergic system of the caudate nucleus on EEG indices of feeding behavior in the cat].

The antagonistic dynamics of appearance of 30 c/s EEG-rhythm in the amygdala and 18 c/s rhythm in the parietal cortex during food-procuring behaviour of cats is considered as EEG manifestation of the interaction between motivation and reinforcement mechanisms. The study has not detected any distinct changes in the dynamics of the appearance of these EEG-rhythms after cholinomimetics injections into the caudate nucleus. A conclusion has been made that stimulation of acetylcholinergic structures of the caudate nucleus while depressing the motor component of the food-procuring reflex, does not significantly disturb the above mechanisms of alimentary behaviour.
