Abstract
Effects of glycine on the spontaneous activity of medial vestibular nu cleus (MVN) neurons recorded extracellularly from guinea-pig brainstem slices were investigated. Glycine produced a dose-dependent decrease in the resting discharge rate of all MVN neurons tested, with a mean E C(50) Of 3.9 x 10(-4) M. The inhibitory effect of glycine was reversib ly blocked by strychnine and persisted in a low calcium/high magnesium -containing saline solution. These findings suggest the existence of a direct strychnine-sensitive inhibitory Effect of glycine on guinea-pi g MVN neurons.
