title: [Neurophysiological analysis of efferent-afferent interaction of neurons of the parietal associate cortex in cats].
abstract: Neuronal responses of the parietal associate cortex (field 5) was recorded in waking cat during electrical stimulation of the pyramidal tract axons and afferent stimulation. The electrical stimulation of the pyramid evoked marked responses in 39% of neurons. 87% of these neurons increased spike activity during sematic nociceptive stimulation, 61% of test neurons were activated by light or tonal stimulation. Neuronal activity was recorded during defensive conditioning to the pyramidal tract axons stimulation. It has been shown that conditioned stimulation of the pyramidal tract evoked plastic changes of responses in 66% of neurons of the parietal cortex. These data are discussed relative to the possible functional role of the efferent-afferent interaction to field 5.
