Alterations in Intrinsic Membrane Properties and the Axon Initial Segment in a Mouse Model of Angelman Syndrome

Abstract excerpt

The axon initial segment (AIS) is the site of action potential initiation in neurons. Recent studies have demonstrated activity-dependent regulation of the AIS, including homeostatic changes in AIS length, membrane excitability, and the localization of voltage-gated Na(+) channels. The neurodevelopmental disorder Angelman syndrome (AS) is usually caused by the deletion of small portions of the maternal copy of...
