title: Real-time distribution of linked spike activity in cortical neurons during learning in the cat.
abstract: Analysis of the distribution of linked spike activity showed changes occurring within the structure of interneuron functional connections during learning. In an electric shock defensive reflex, concentration of linked spikes from cat motor cortex neurons was observed on signal presentation, while in a conditioned food-procuring reflex to time, this was confined to the moment at which reinforcement was provided. This can be regarded as the appearance of a reflex at the level of interneuron interactions. This conclusion is supported by the observation that in well-trained animals, concentrations of linked spikes could be seen at the place of the conditioned reflex response, even in the absence of defensive and food-procuring movements.
