A) is cancelled out by an inhibitory postsynaptic potential
B) has a hyperpolarizing effect
C) will drive the membrane away from its potential
D) is summed with an inhibitory postsynaptic potential at the input zone of a neuron

E) works so that only one impulse can be received at a time

Quizplus · Accepted Answer

An excitatory postsynaptic potential (EPSP) can be summed with an inhibitory postsynaptic potential (IPSP) at the input zone of a neuron, affecting the overall membrane potential and influencing whether an action potential will be generated.
