The intracellular microelectrode recordings from the spinal drosal horn of C5 - T1 segments were used to search and identify the spinal neurons. A total of 53 neurons responding to the stimulation of both STN and HG was recorded intracellularly. 24 and 29 of them were found to antidromically and synaptically respond to the stimulation of STN, respectively. These neurons were mainly distributed in the laminae III - Vl of spinal dorsal horn. The results indicate that (i) some spinal neurons can receive somatic afferent inputs from HG and convey them to the visceral sensory nucleus - STN; (ii) the other spinal neurons receive afferent impulse from both the STN and HG; (iii) the convergence and integration between somatic and visceral sensory inputs might occur in these spinal neurons and STN.展开更多
