Capturing and Manipulating Activated Neuronal Ensembles with CANE Delineates a Hypothalamic Social-Fear Circuit.

abstract：:Action potentials initiate in the axon initial segment (AIS), a specialized compartment enriched with Na(+) and K(+) channels. Recently, we found that T- and R-type Ca(2+) channels are concentrated in the AIS, where they contribute to local subthreshold membrane depolarization and thereby influence action potential in...
