If a postsynaptic cell is stimulated to threshold by temporal summation this implies that_________ .
A) the presynaptic neuron is sending frequent IPSP
B) a presynaptic neuron is sending frequent EPSP
C) the postsynaptic cell is sending frequent action potential
D) the postsynaptic cell can be influenced by only one presynaptic cell

Temporal summation is the process by which multiple EPSPs from a single presynaptic neuron add up over time, eventually reaching the threshold for the postsynaptic neuron to fire an action potential. Therefore, frequent EPSPs from a presynaptic neuron are responsible for temporal summation.
