What part of a neuron functions as the integrating center, where the membrane potential reflects the summed effect of all EPSPs and IPSPs?
A) the nuclear membrane
B) region of the cell body where dendrites converge
C) the presynaptic terminals of the longest axon
D) the axon hillock

Question

Quizplus · Accepted Answer

The axon hillock functions as the integrating center in a neuron. It is the area where the cell body transitions to the axon, and it is responsible for integrating all excitatory and inhibitory postsynaptic potentials (EPSPs and IPSPs) to determine whether the neuron will fire an action potential.
