channels they express. From among the more than 70 different K+ channel genes …

[HTML][HTML] Redistribution of Kv1 and Kv7 enhances neuronal excitability during structural axon initial segment plasticity

H Kuba, R Yamada, G Ishiguro, R Adachi - Nature communications, 2015 - nature.com
Structural plasticity of the axon initial segment (AIS), the trigger zone of neurons, is a
