A postsynaptic neuron will have an Excitatory Postsynaptic Potential (EPSP)when
A)chemically-regulated potassium channels are open and potassium is diffusing out of the cell.
B)more calcium ions than usual diffuse into the neuron.
C)chemically-regulated sodium channels are open and sodium is diffusing into the cell.
D)the neuron is hyperpolarized.
E)more potassium ions than usual diffuse out of the neuron.

Question
