For the Following Questions, Assume a Hypothetical Postsynaptic Neuron Has

Multiple Choice

For the following questions, assume a hypothetical postsynaptic neuron has three presynaptic inputs: neurons X, Y, and Z. Also, assume neuron Z is excitatory. If neurons X and Z receive simultaneous stimulation, what change would you expect in the postsynaptic neuron?

A) a single EPSP
B) a single IPSP
C) temporal summation of EPSPs
D) spatial summation of EPSPs
E) an IPSP and EPSP would cancel each other out, so there would be essentially no change in potential in the postsynaptic neuron
