Inhibitory control - Wikipedia

In neuroscience, an excitatory postsynaptic potential (EPSP) is a postsynaptic potential that makes the postsynaptic neuron more likely to fire an action potential. This temporary depolarization of postsynaptic membrane potential, caused by the flow of positively charged ions into the postsynaptic cell, is a result of opening ligand-gated ion channels. These are the opposite of inhibitory post… Webb억제성 시냅스후 전위 ( 영어: inhibitory postsynaptic potential, IPSP )는 향후 활동전위 가 시냅스후 뉴런에서 또는 알파운동뉴런 에서 일어날 확률을 감소시키는 시냅스후 전위 이다.
