[The inhibitory effect of amygdaloid stimulation on the "on-off" response of medial geniculate body neurons in rabbits].
Experiments were performed on 23 New Zealand rabbits immobilized with Flaxedil. The characteristics of on-off responses of medial geniculate body (MGB) neurons to tone bursts of varying frequency, intensity and duration were affected by lateral amygdaloid nucleus (LAm) stimulation, which was in form of altering the pattern of discharge or complete suppression. The effect also varied with the changes of the interval between amygdaloid stimulation and the tone bursts. The results of the present work show that LAm could modulate temporal processing of auditory information.
