Question

A neuron can receive thousands of EPSPs from different neurons, and responds by triggering or not triggering an action potential. This addition and response to the net effect of postsynaptic potentials is called __________.
a. temporal summation
b. neural summation
c. spatial summation
d. neuronal coding
e. recruitment

Answer 1

Answer: This addition and response to the net effect of postsynaptic potentials is called SPATIAL SUMMATION. Option C is correct..

Explanation: Spatial summation is the effect of triggering an action potential in a neuron from one or more presynaptic neurons. This occurs when more than one excitatory postsynaptic potential (EPSP) originates simultaneously and a different part of the neurone.
