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

Question

Quizplus · Accepted Answer

Temporal summation occurs when a single presynaptic neuron sends frequent EPSPs to a postsynaptic neuron, causing the postsynaptic neuron to become depolarized to threshold and fire an action potential. Therefore, the correct choice is C, "a presynaptic neuron is sending frequent EPSPs." The other choices are incorrect as they do not accurately describe temporal summation.
