The summing of many EPSPs from a single pre-synaptic neuron over a short time period is called
A) spatial summation.
B) temporal summation.
C) IPSP.
D) hyperpolarization.

Question

Quizplus · Accepted Answer

Temporal summation refers to the summing of EPSPs from a single pre-synaptic neuron over a short time period. Spatial summation occurs when multiple pre-synaptic neurons release neurotransmitters onto a single post-synaptic neuron. IPSPs are inhibitory post-synaptic potentials and hyperpolarization is a shift in the resting potential of a neuron towards a more negative value. Neither of these options describe the scenario described in the question.
