The exercise pressor reflex: evidence for an afferent pressor pathway outside the dorsolateral sulcus region

Abstract

Pressor reflexes evoked by muscle contraction following stimulation of the cut distal portions of the L 7 and S 1 ventral roots were the dorsolateral sulcus region of the T 13-L 1 spinal cord, indicatining that this area is not essential for mediation of these reflexes. Additional evidence suggested that the pathway responsible for the exercise pressor reflex located in the surviving spinal cord is most likely bilateral.
