SG神经元的基本电生理学特点

Electrophysiologic characteristics of SG neurons

Characteristics	Total	No rebound	Rebound without spike	Rebound with spike
RMP: Resting membrane potential; Cm: Membrane capacitance; AP-T: Threshold of action potential. AP-A: Amplitude of action potential; AP-HF: Half width of action potential. The action potential thresholds in no rebound depolarization group are significantly higher than those in rebound depolarization with spike group (*P＜0.05).
