What permeability changes would you expect to occur at the postsynaptic neuron when presynaptic neuron Y is stimulated? (Remember that the postsynaptic neuron becomes depolarized by presynaptic neuron Y.) A)increased P_Na+ and P_K+ B)increased P_K+ or P_Cl- C) increased P_A- D) increased P_Ca2+

When a postsynaptic neuron becomes depolarized, it is typically due to an increase in sodium (Na+) permeability, which allows Na+ ions to flow into the neuron, making the inside more positive. Potassium (K+) permeability may also increase to help restore the resting potential after depolarization.
