Voltage-gated Na channels are expressed in all neurons, and are responsible for the upstroke of the action potential. They are part of a complex of proteins that includes pore-forming α subunits and auxiliary subunits that modify their trafficking, gating, and function. The modulation of Na channels by auxiliary subunits is...
Following dopaminergic denervation in Parkinson's Disease, firing patterns in several basal ganglia neuron populations are pathologically altered. In the globus pallidus (GP), this manifests as a loss of autonomous, rhythmic, high-frequency pacemaking and an appearance of correlated, oscillatory bursting. This oscillatory bursting is best disrupted through high-frequency stimulation of affected...
