title: [Comparative analysis of the interactions between spontaneous active neurons of the sensomotor cortex of kittens and adult cats].
abstract: The character of functional interneuronal relations in the sensorimotor cortex during spontaneous neural activity in kitten and adult cats immobilized with d-tubocurarine, was studied by the method of cross-correlations of two impulse series. The data obtained by computation revealed specific age-related interneuronal connections in investigated groups of animals. In kitten aged up to 10 days, the highest percentage of the functional connections was observed which were established mainly due to the influence of a common source. In other groups of animals (kittens of 20, 30 days of postnatal life, adult cats) the common source did not play a significant role in the formation of interneuronal connections. The results showed that inhibitory connections between neurones-are established to the end of the first month of the postnatal life.
