If presynaptic neuron Z is repeatedly stimulated very rapidly, what change would you expect to occur in the postsynaptic neuron?
A)a single EPSP
B)a single IPSP
C) temporal summation of EPSPs
D) spatial summation of EPSPs

Rapid stimulation of presynaptic neuron Z would lead to temporal summation of EPSPs in the postsynaptic neuron. This is because the closely timed action potentials in the presynaptic neuron would result in multiple EPSPs being generated and overlapping in time, which would summate and reach the threshold for firing an action potential in the postsynaptic neuron.
