摘要：

THE question is raised whether the sequence of spikes of a cortical neuron, i.e. its spike train, is related to cognitive functions. Neuronal patterns of firing in the inferotemporal cortex of monkeys performing visual delayed-matching tasks showed that short-term memory was accompanied by decreased bursting and changes in the incidence of recurrent spike-interval patterns. The temporal structure of the spike train suggests an inverse relationship between the incidence of repeated patterns and the degree of selectivity of sustained firing frequency elicited by the memorandum (sample stimulus).
