SPLANCHNIC AFFERENT PATHWAYS IN THE CENTRAL NERVOUS SYSTEM

Abstract
Splanchnic afferent pathways in the central nervous system were traced by stimulating the splanchnic nerves electrically and recording action potentials in the brain and spinal cord. A pathway consistent with fibers from the pacinian corpuscles was found in the ipsilateral posterior funiculus, and contralateral medial lemniscus and nucleus ventralis postero-lateralis of the thalamus. Slower responses were found in the region of the lateral spinothalamic tracts in the cord and medulla, and in the posterior hypothalamus.
