Abstract
Whole cell voltage-clamp recording were made from cultured rat neostriatal neurons. Depolarizing voltage commands evoked transient and sustained outward K-currents. The transient K-current was activated by depolarizing commands beyond -50 mV; peak current was dependent upon holding potential. Bath application of 4-aminopyridine, but not inorganic calcium channel blockers (Cd, Co, Mn), attenuated the transient current. Reversal was near the K-equilibrium potential. These properties suggest that this transient K-current is similar to the A-current described in a number of other neurons.
