[Participation of frontal lobe neurons in the organization of successive inhibition and disinhibition of conditioned reflexes in the dog].

Neuronal activity in g. proreus was studied during classical secretory conditioning and its differentiation in dogs. Three types of changes in neuronal reaction pattern were identified during differential conditioned stimulus compared to the pattern observed during positive conditioned stimulus. It has been shown that signal significance of the conditioned stimulus may be coded by specific distribution of interspike intervals in response to different conditioned stimuli. In situation of successive inhibition or disinhibition of the differentiation some neurones displayed simultaneous appearance of interspike intervals specific for responses to current and previously presented conditioned stimuli.
