Initial segment of axon
WebbThe axon initial segment (AIS) is a crucial region in neurons required for the generation of action potentials. The scope of this research aims to elucidate the localization of certain potassium and calcium channels in the AIS and determine what anchoring proteins may play a role in their localization.
