[Participation of GABA and glycine in the formation of somato-sympathetic reflexes]

Abstract

Experiments were conducted on cats with intact spinal cord, and after spinalization a study was made of the action of strychnine and picrotoxin (synaptic GABA and glycine antagonists) on the components of somatosynaptic reflexes caused by stimulation of the skin and muscular intercostal afferents. Induced potentials were recorded in the white ramus of the third thoracic segment. The action of strychnine and picrotoxin on the values of different reflex components was not identical; this pointed to a different localization of the inhibitory action of GABA and glycine in the central link of the somatosympathetic reflex arch.
