在麻醉猫的膀胱传入神经中，受体功能和传导速度之间存在相关性（24）。单单位记录被用来识别初级传入的生理和电刺激激活。确定了三种类型的传入神经：逼尿肌传入神经，其响应于逼尿肌肌肉组织中的张力变化;传入神经，其响应于粘膜-粘膜下表面的机械扩张;和位于囊周组织中的机械感受器。逼尿肌传入速度低于16米/秒，粘膜传入速度在18至22米/秒之间，膀胱周围传入速度在25至40米/秒之间。
A correlation between receptor function and conduction velocity was made for bladder afferents in the anesthetized cat (24). Single-unit recordings were used to identify primary afferents which were activated by physiological and electrical stimulation. Three types of afferents were identified: Detrusor afferents which responded to tension changes in the detrusor musculature; afferents which responded to mechanical distention of the mucosal-submucosal surface; and mechanoreceptors which were located in the perivesicular tissue. Detrusor afferents conducted below 16 m/sec, mucosal afferents between 18 and 22 m/sec, and perivesicular afferents between 25 and 40 m/sec.
