[The distribution in real time of the spike train activity in the cortical neurons of cats during learning].
Analysis of the dynamics of distribution of coincident impulses in pairs of neurons revealed modifications in the structure of neuronal interaction in the process of learning. In electrodefensive sound conditioning coincident paired impulses of the neurons in cat's motor cortex were timed to the moment of the conditioned stimulus presentation. In food-procuring time conditioning coincident impulses were concentrated around the moment of the reinforcement administration. The described temporal pattern of coincident impulse distribution is considered as a manifestation of a conditioned reaction at the level of neuronal interaction. This conclusion is confirmed by the finding that coincident impulses may be grouped within the period of expected conditioned reaction even in the absence of the defensive or food-procuring movement in well-trained cats.
