Somatic/visceral sensory neurons in the spinal cord and synaptic/junctional activity in the spinal ganglion

Somato-visceral interaction or acupoint-visceral interaction is an important subject that greatly concerns scholars of both Chinese traditional and Western modern medicine. The role of our newly discovered spinal projection neurons and type A or C spinal ganglion neurons in convergence and integration of somato-visceral sensation is introduced. The possible challenge brought about by these related results onto some traditional concepts in neuroscience is also discussed.
