    Abstract:
    Neuronal activity of the orbital cortex, the caudate nucleus and the amygdala were studied in chronic experiments on dogs and cats by the method of alimentary and defensive conditioned reflexes. A spatial distribution of neurones involved in the alimentary and defensive conditioned reflexes, was revealed in the caudate nucleus head. The units responding to conditioned alimentary stimuli are localized primarily in the ventral segment. Similarity of responses to surroundings and to trigger conditioned alimentary stimuli was found between the units of the ventral segment in the caudate nucleus head and of the amygdala basolateral part. The influence of stimulation of the amygdala on the orbital cortex units was established in the alimentary conditioned reflex in dogs. A conclusion has been drawn that in elaboration of an alimentary conditioned reflex the neurones of three levels become organized into a definite system, providing for an adequate reaction of the organism to the conditioned stimulus.
