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.
