Time course of NT-3 effect on BK current. (A) The BK current was increased by 50 ng/ml NT-3 (N) (five out of six cells). The effect was completely blocked by 1 μM paxilline (P). (B) BK current was increased by 10 ng/ml NT-3 (three out of seven cells). (C) In buffer alone (Control), the BK current was constant for 2 hr in five out of five cells examined. (T = 3 mM TEA.)
