Axon Initial Segment Structure and Function in Health and Disease
PM Jenkins, KJ Bender - Physiological Reviews, 2024 - journals.physiology.org
At the simplest level, neurons are structured to integrate synaptic input and perform
computational transforms on that input, converting it into an action potential (AP) code. This …
