Abstract:
Effects of temperature and anesthesia on various excitability indexes of sciatic—peronael nerve were observed in toads. The results show that standard electrical quantity(a) changes regularly with the change of excitability. The higher excitability, the less the "a" value. But "b" in Weiss's fomula, chronaxie (Chr), rheobase (Rh), and intensity-duration curve do not indicate excitability. The time constant (RC)of the cell membrane is not related to the changes of excitability. Thus, "a" is an actual index of measuring excitability.
