Subthreshold membrane properties of basket cells in monkey and rat. A: voltage responses to the hyperpolarizing and depolarizing current steps (representative examples from monkey and rat). Note the depolarizing sag on hyperpolarizing responses and the hump on depolarizing responses in monkey basket cells (arrows). B: current–voltage plots for traces shown in A. C: synaptic blockers (CNQX, 20 μM; APV, 50 μM; gabazine, 4.5–6 μM) did not produce any significant changes in input resistance in both monkey and rat basket cells. D: different examples of depolarizing sags (arrows) and rebound depolarizations (arrowheads) in monkey basket cells. Traces from rat basket cells lack both depolarizing sag and rebound depolarization. E: ZD7288 (20 μM) eliminated depolarizing sag in monkey basket cells (n = 4).
