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

Question

Quizplus · Accepted Answer

The summing of EPSPs over a short time period is called temporal summation. Spatial summation refers to the summing of EPSPs from multiple pre-synaptic neurons on a single post-synaptic neuron. Irritability refers to the responsiveness of a neuron to a stimulus, while hyperpolarization refers to a state in which the membrane potential of a neuron becomes more negative than its resting potential.
