[Overall electrical responses of the superior olivary complex to amplitude-modulated signals]. 1977

N G Andreeva, and Ta Tun Lan

EPs in the auditory nuclei of the horseshoe bats to amplitude--modulated signals (AMS) were studied. The reaction of synchronization in cochlear nuclei (only for fast component) and in superior olivary complex (both for fast and slow components) in frequency range of modulation form 50 to 2000/sec was noted. The synchronized responses in the inferior colliculus occurred only to the frequency of modulation lower than 150/sec. No such reaction was recorded in the medial geniculate bodies. For the superior olivary complex the lowest threshold of the synchronization was in the range of 15-30 and 80-86 kHz. The amplitude of the synchronizing response was the function of the coefficient of modulation, frequency of modulation, and the space localization of the sound source.

D009847	Olivary Nucleus	A brainstem nuclear complex. in the hindbrain, also referred to as the olivary body. The olivary nuclear complex is a part of the MEDULLA OBLONGATA and the PONTINE TEGMENTUM. It is involved with motor control and is a major source of sensory input to the CEREBELLUM.
