以往研究证明，大鼠腰骶髓后连合核（DCN）不仅是盆腔内脏感觉的中继站，也接受后肢躯体感觉的传入，同时二者的终未共同汇聚于同一后连合核的投射神经元的树突上，因而推测DCN可能与内脏和躯体感觉的调控有关。在该区域内还发现有大量的SP样、CGRP等与传递伤害性信息有关的神
Previous studies have shown that rat lumbosacral dorsal commissural nucleus (DCN) is not only a relay of pelvic visceral sensation, but also accept the somatosensory afferent of the hind limbs, while the two have not co-converge on the projection of the same posterior nucleus Yuan dendrites, suggesting that DCN may be related to visceral and somatic sensory regulation. In the area also found a large number of SP-like, CGRP, etc. and the transmission of harmful information related to God
