Definitions:

Axon Hillock

The cone-shaped region of an axon of a neuron where the axon joins the cell body, and where action potentials are initiated.

Initial Segment

The part of a neuron where the axon originates from the cell body, crucial for the initiation of action potentials.

EPSPs

Excitatory PostSynaptic Potentials, which are increases in post-synaptic membrane potential caused by the flow of positively charged ions into the post-synaptic cell, potentially leading to action potential.

Temporal Summation

A process by which multiple subthreshold excitatory post-synaptic potentials (EPSPs) combine within a brief period to produce a larger postsynaptic potential.
