Kv1 potassium channel complexes in vivo require Kvbeta2 subunits in dorsal spinal neurons.

abstract：:Persistent inward currents are important to motoneuron excitability and firing behaviors and also have been implicated in excitotoxicity. In particular, L-type Ca2+ channels, usually located on motoneuron dendrites, play a primary role in amplification of synaptic inputs. However, recent experimental findings on L-typ...
