Question

Quizplus · Accepted Answer

An action potential is generated at the axon hillock of a neuron when the sum of the excitatory and inhibitory postsynaptic potentials reaches a threshold level. This can be caused by stimulation of any portion of the dendrites of the neuron and/or input from various presynaptic cells.
