Axon hillock

Encyclopedia : A : AX : AXO : Axon hillock

The Axon Hillock is the anatomical part of a neuron that connects the cell body called soma (biology) to the axon. It is attributed as the place where Inhibitory Postsynaptic Potentials (IPSPs) and Excitatory Postsynaptic Potentials (EPSPs) from numerous synaptic inputs on the dendrites or cell body accumulate. If the accumulated potential reaches the threshold, an action potential propagates through the rest of the axon (or "backwards" towards the dendrites as seen in backpropagation).
