[Evoked auditory cortex potentials of wakeful dogs in response to paired clicks].

EP to a test click appears in the auditory cortex of alert intact dogs in 30--40 ms after the conditioning click (period of the so called absolute refractory state). The curve of the recovery of the second EP has a complex periodic character with two stages of complete recovery of the early EP complex amplitude: rapid initial after 80--180 ms, and final, 280--430 ms after presentation of the conditioning click.
