An EPSP

Multiple Choice

An EPSP:

A) is a direct result of the opening of ligand-gated channels permeable to both Na⁺ and K⁺ ions.
B) is a direct result of the opening of voltage-gated channels permeable to both Na⁺ and K⁺ ions.
C) stabilizes the membrane to remain at its resting potential.
D) opens voltage-gated Ca²⁺ channels in the presynaptic membrane.
E) occurs when voltage-gated Cl- channels open in a postsynaptic cell membrane.
