τInact, inactivation time constant; τDeact, deactivation time constant. Whole-cell outward current was evoked by a 400 ms depolarizing step from −80 to +40 mV. Values are means ± s.e.m. and n is the number of neurons sampled. Time constant values were estimated from exponential fits to the inactivating or deactivating portions of the currents. * Value after BDNF treatment (15 min) is significantly different from pretreatment value by Student's paired t test at P < 0.05.
