Question

Quizplus · Accepted Answer

The axon hillock is the site where EPSPs (excitatory postsynaptic potentials) and IPSPs (inhibitory postsynaptic potentials) are integrated. This integration determines whether or not an action potential will be generated and propagated down the axon. Chemical and electrical synapses occur at the dendritic membrane and synaptic knob, respectively, but they do not play a direct role in EPSP/IPSP integration.
