[Neuronal reactions of the substantia innominata in the cat during an instrumental conditioned reflex].
Neuronal impulse activity in the substantia innominata has been studied in cats during conditional placing with food reinforcement. 44.3% of neurons changed their activity in trained cats. Activity of 24.3 neurons correlated with conditional sound stimuli. Reactions correlating with the conditional movement were weak. The most intensive and prolonging response was observed during food reinforcement. In some cases this reaction appeared 500 ms before the reinforcement. It is assumed that involvement of cholinergic neurons of the substantia innominata in reinforcement assisted trace phenomenon maintenance in neocortex neurons.
