title: [Responses of the auditory region of the dog cortex to paired clicks repeatedly presented in a standard series].
abstract: A study was made of evoked potentials (EP) in the dog auditory cortex to systematically presented series of acoustic stimuli consisting of five pairs of clicks with a 150 to 300 msec interstimuli interval within the pair, for different dogs. As such series were presented, a dependence developed of amplitude characteristics of averaged EPs on the place of paired stimulation in the five-term series. The correlation of amplitudes inside each pair was likewise determined by the place of the pair in the series. The index of the EP amplitude recovery was smaller in the case of the first and fifth places of the pair in the series and greater in the middle places of the series. Reinforcement of the five-term series of paired clicks with electro-cutaneous stimulation of the paw and elaboration of a conditioned defensive reflex changed the established correlation of EP amplitudes. In the experiment the index of EP amplitude recovery depended on the signal significance of the presented click series.
