Experience Shapes Chandelier Cell Function and Structure in the Visual Cortex

This study shows that chandelier cells in the visual cortex change their function and structure with experience, responding more to arousal-related events and showing plasticity in their connections.

Sodium channel endocytosis drives axon initial segment plasticity

The paper shows that NMDA receptor-mediated long-term synaptic depression causes rapid endocytosis of sodium channels from the distal AIS, revealing a mechanism for activity-dependent AIS reorganization.

Sensory input drives rapid homeostatic scaling of the axon initial segment in mouse barrel cortex

The paper shows sensory input drives rapid homeostatic scaling of the axon initial segment in mouse barrel cortex, with sensory deprivation increasing AIS length and excitability, while enrichment shortens AIS and reduces action potential generation.
