The most common mechanism for producing a fast EPSP involves which of the following?
A)closing of sodium- selective channels
B)opening of sodium- selective channels
C)closing of potassium- selective channels
D)opening of potassium- selective channels
E)opening of channels that permit both sodium and potassium to flow through

Question

Quizplus · Accepted Answer

Fast excitatory postsynaptic potentials (EPSPs) are typically generated by the opening of ion channels that allow both sodium (Na+) and potassium (K+) ions to flow through, such as those activated by neurotransmitters like glutamate at AMPA receptors. This results in depolarization of the postsynaptic membrane.
