Responses to 1 Hz (arrow; left) and to 20 Hz (horizontal bars, right), 0.3 ms in duration for 1 s. A, under control conditions, prominent EFS evoked EJPs were followed by smaller, more slowly developing IJPs. B, l‐NNA (100 μm) inhibited IJPs and potentiated the amplitude of EJPs. C and D, benzbromarone (1–3 μm) caused a reduction in EFS evoked EJPs. E, EJPs were inhibited at a concentration of 5 μm. Benzbromarone also caused hyperpolarization in membrane potential.
