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.If presynaptic neurons X and Z are stimulated simultaneously, what change would be expected to occur in the postsynaptic neuron
A)a single EPSP
B)a single IPSP
C)temporal summation of EPSPs
D)IPSP and EPSP would cancel each other out, so there would be essentially no change in potential in the postsynaptic neuron.
