[Responses of the neurons of the parietal associative cortex of the cat brain to indifferent and conditioned acoustic stimuli].
Neuronal responses of the associative cortex (field 5) to indifferent and to conditioned sound stimuli were studied. The number of neurons responding to the conditioned sound during classical reflex increased two times. A percentage of inhibitory responses of neurons to conditioned acoustic stimulus during placing reflex grew. Neurons were found which responded to the conditioned sound only in the absence of the conditioned movement during instrumental food reflex. Despite the fact that the associative cortex participates in the analysis of sensory signals and in evaluation of their biological significance, its main functional property is its involvement in the initiation of behavioral reaction to the conditioned stimulus.
