primary driver of behavioral learning and development. How this microscopic-macroscopic …

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 …

Axo-axonic synaptic input drives homeostatic plasticity by tuning the axon initial segment structurally and functionally

R Zhao, B Ren, Y Xiao, J Tian, Y Zou, J Wei, Y Qi… - Science …, 2024 - science.org
