突觸後電位(Postsynaptic Potentials) | 私立大學五星教授網

EPSP也可能是由於流出的正電荷減少所致，而IPSP有時是由於正電荷流出量增加所致。引起EPSP的離子流是興奮性突觸後電流。 該單一EPSP不能使膜充分地去極化以產生 ...

突觸後電位(Postsynaptic Potentials) ... 3. IPSPs：若打開Cl-通道(流入細胞)及K+通道(流出細胞)使膜電位更負，就不可能讓軸丘產生動作電位，這時稱為抑制性的突觸後電位。

抑制性突觸後電位（IPSP）造成突觸後細胞的局部超極化，其作用是降低突觸後細胞發生動作電位的概率，所以是EPSP的拮抗者。中樞神經系統中的大多數神經元都同時收到EPSP和IPSP的 ...

電位產生過極化，這種使突觸後神經元的靜止膜電位更負的變化. ，稱為抑制性突觸後電位(inhibitory postsynaptic potential. ；IPSP)。 ... postsynaptic potential；EPSP)。

EPSP IPSP(Excitatory / Inhibitory postsynaptic potential)(兴奋性突触后电位/抑制性突触后电位)，形成是兴奋性递质，使某些离子通道开放，后膜对Na+和K+的通透性增大， ...

PSPs are called excitatory (or EPSPs) if they increase the likelihood of a postsynaptic action potential occurring, and inhibitory (or IPSPs) if they decrease ...

2020年11月10日 — EPSP is an excitatory postsynaptic potential that occurs when a neurotransmitter like glutamate binds to receptors on the postsynaptic ...

An IPSP is received when an inhibitory presynaptic cell, connected to the dendrite, fires an action potential. The IPSP signal is propagated down the dendrite ...
