Effects of periaqueductal gray and raphe magnus stimulation on the responses of spinocervical and other ascending projection neurons to non-noxious inputs.

Abstract

Experiments were performed in cats anesthetized with alpha-chloralose to examine the effects of stimulating in the periaqueductal gray (PAG) and nucleus raphe magnus (NRM) on the responses of spinocervical cells and unidentified ascending projection neurons to non-noxious peripheral stimuli. Peripheral stimuli consisted of low amplitude sinusoidal… (More)
