• Whole cell recordings from acutely dissociated neurons exhibited a R-type currents that were characterized as HVA by their rapid deactivation kinetics, half-activation and half-inactivation voltages, and sensitivity to depolarized holding potentials. In neocortical pyramidal neurons these currents inactivated at more negative potentials than in medium spiny neurons Show Other
