Somatovisceral Pathway: Rapidly Conducting Fibers in the Spinal Cord

Abstract
Fibers that respond to distension of hollow viscera and to mechanical stimulation of somatic structures were found primarily near the ventromedian fissure of the upper lumbar spinal cord. These fibers could be directly excited by electrical stimulation at C1. The average conduction velocity for these fibers was 68.6 meters per second.
