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 neuron Z is repeatedly stimulated very rapidly, 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)spatial summation of EPSPs

Quizplus · Accepted Answer

Temporal summation of EPSPs would occur if presynaptic neuron Z is repeatedly stimulated very rapidly. This means that the EPSPs from presynaptic neuron Z would be added together, leading to a stronger depolarization of the postsynaptic neuron and increasing the likelihood of an action potential.
