[Temporal and phase effects in the total synchronized response of the inferior colliculus of the corpora quadrigemina upon binaural acoustic stimulation].

Following binaural stimulation with tones of different interaural time delays, the frequency-following response (FFR) recorded in anaesthetized cats showed periodical changes in the amplitude. Their period was equal to the period of the tones. The "characteristic" delay delay was a function of both the signal frequency and electrode position. The sensitivity of the frequency-following response to the phase relations between the components of the complex sound signal depended to a great extent on the interaural time delay.
