  • Title: [Dynamics of neuronal responses of the auditory zone of the cortex of wakeful cats during the process of elaboration of a defensive conditioned reflex to acoustic stimulation].

    Abstract:
    In chronic experiments on cats the neuronal responses (recording by means of glass microelectrodes) of auditory cortex I were studied during elaboration of a defensive conditioned reflex to a sound stimulus. During conditioning the biphasic reactions with a rather short-latent (50-100 ms) and more long-latent (400-500 and 800-900 ms) activation were predominant. The neighbouring neurons whose responses were recorded by the same microelectrode were involved into the activity more intensively. A differentiating stimulus in 70% of applications caused distinct changes in neuronal activity (predominantly of activation type). Analysis of the dynamics of responses of the same neuron during a great deal of combinations and its comparison with the formation of a motor reaction showed no direct correlation between the two events.
