XYZ For the Following Questions, Assume a Hypothetical Postsynaptic Neuron Has

XYZ
For the following questions, assume a hypothetical postsynaptic neuron has three presynaptic inputs: X, Y, and Z. Also assume that presynaptic neurons Y and Z are excitatory.
-Refer to the text.What permeability changes would be expected 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 PNa⁺ and PK⁺
B) increased PK⁺ or PCl^-
C) increased P_A-
D) increased PCa²⁺
