[Selectivity of trace reactions of medial geniculate neurons to the rate of simulated movement of a sound source in the cat].
33 out of 90 neurons of the cat medial geniculate body revealed the selectivity of their afterdischarges to movement of sound when velocity of the movement changed from 30 to 180 deg/s. There was a specific velocity of the movement for each neuron. 76% of the neurons preferred the movement of 45--90 deg/s. 9 neurons had a periodic character of responses. The selective afterdischarges occurred in 39% of dorsal neurons and in 39% of ventral ones. The afterdischarges can be dependent on the direction of sound source movement, too.
