Although most sensory neurons convey temporally coded impulses to the central nervous system, certain nonspiking receptors use only graded afferent signals. Each of three large nerve fibers from the lobster oval organ, a mechanoreceptor subserving ventilation, carry both impulses and graded potentials. Thus, both impulse frequency and receptor potential amplitude are available for information transfer.
尽管大多数感觉神经元将时间编码的冲动传递到中枢神经系统，但某些无峰电位感受器仅使用分级传入信号。龙虾椭圆形器官（一种服务于通气的机械感受器）的三条大神经纤维中的每一条都同时携带冲动和分级电位。因此，冲动频率和感受器电位幅度都可用于信息传递。
