title: [Responses of neurons in the SI zone during a defensive conditioned reflex to sound].
abstract: Responses of single neurons in the primary projection zone of the somatosensory cortex to conditioned and electrocutaneous reinforcing stimuli were investigated in chronic experiments on cats with a preliminary developed sound conditioned defensive reflex. Five types of neuronal responses to reinforcing stimulus during application of combination were separated; such differentiation was impossible for neuronal responses appearing in the place of the absent reinforcing stimulus. A comparison of neuronal spike activity with the conditioned movement reaction revealed strict correlation between these processes. The conditioned movement reaction usually preceeded the conditioned neuronal response.
