55. Which statement about hyperpolarization of a neuron is true? When hyperpolarization occurs,
(A) membrane potential is more negative than during resting potential.
(B) membrane potential is closer to Na+ equilibrium potential (ENa) than it is to EK.
(C) Na+ and/or Cl− channels are open.
(D) if it occurs in a downstream neuron, exciting postsynaptic potentials (EPSPs) are more likely to be generated than are inhibitory PSPs (IPSPs).
(E) generation of action potentials is likely to occur.
