Neostriatum spiny direct pathway neuronSomaI A.The contribution of a fast (IAt), and a slowly (IAs)-inactivating A-currents were studied in slices. The results suggest a role for these currents to define the limits on the depolarized state (Nisenbaum ES and Wilson CJ, 1995237 ). With whole-cell patch clamp, two types of A-current were found in rat neostriatal neurons, one similar to previous descriptions in mammals and a second activated at considerably more depolarized potentials (Surmeier DJ et al, 1989239 ). A slowly inactivating A current has also been studied (Gabel LA and Nisenbaum ES, 1998246 ).
