Question

multiple choice question an - postsynaptic potential involves the opening of sodium channels, depolarizing the membrane, and bringing it closer to a threshold level. o excitatory o inhibitory need help? review these concept resources.

Explanation:

Excitatory postsynaptic potential (EPSP) occurs when sodium channels open, depolarizing the membrane and bringing it closer to the threshold for an action - potential. Inhibitory postsynaptic potential (IPSP) hyperpolarizes the membrane, moving it away from the threshold.

Answer:

B. excitatory
