Brief hyperpolarizing afterpotential
repolarizing phase가 RP에 이르렀을 때 gK 가 resting level에
못 미치며, gNa보다 상대적으로 높다.
따라서 MP이 EK에 더 가깝다.
Prolonged hyperpolarizing afterpotnetials
- summate when excitation is repeated at a high rate
- pronounced in the very thin nerve fibers of vertebrates
- produced by an electrogenic Na+ pump
