Abstract
Unit activity of neurons in the visual and parietal brain cortical areas was recorded in cats in the course of feeding behavior. The cells had individual discharge patterns at successive stages of behavior. Rearrangements of patterns in the cortical areas under study depended on modality of a conditioned stimulus, feeding motivation level, and efficiency of the obtaining of intermediate results of behavioral acts. The distribution of impulse flow at the nerve cell axon reflects the dynamics of its integrative activity determined by preceding state of the neuron and current synaptic activation against the background of development of key mechanisms of the functional system of the behavioral act.
