秦秉志等以及另外一些作者曾发现膀胱的内脏初级传入神经元向骶、尾髓后连合核区有较密集的投射。有人推测,此区是尿意感觉的中继处。另外,自 Barrington 以来,一些作者认为脑桥吻端的背外侧被盖核(TLD)和排尿反射有关。为了探索此两区之间的形态学联系及其与排尿反射机能的关系, Qin and others, as well as other authors, have found that the visceral primary afferent neurons of the bladder project more densely into the sacral and posterior commissural nucleus. Someone speculated that this area is the urinary feeling of the relay office. In addition, some authors have suggested since the Barrington that the dorsolateral pons of the pons are related to the capsular (TLD) and voiding reflexes. In order to explore the morphological connection between the two regions and their relationship with urinary reflex function,
