The Action Potential
... The depolarization phase of action potential is abrupt and very rapid: in takes place in less than one milisecond. Soon after reaching the maximum peak of depolarization ( which inverts the membrane potential to some +10 to+ 20 mV), it begins to return to normal, that is, towards its value at rest. ...

Normally, Ndfip1 is only protective in a small number of neurons following injury, due to an unknown reason. However, since all neurons express lo ...
