Effects of TPEN on the recovery of I_A from inactivation in the hippocampal neurons treated with Aβ_25–35. a Typical example of I_A recovery traces from inactivation obtained in the hippocampal neurons (left) and record protocol (right). b Recovery curves of I_A from inactivation in the different treatments. c Time constant of the recovery curves for I_A in the different treatments. The data are presented as means ± SEMs; ^*p < 0.05 and ^**p < 0.01 versus the control group; ^#p < 0.05 and ^##p < 0.01 versus the Aβ group; n = 24 for the control group; n = 21 for the Aβ group; n = 20 for the Aβ + TPEN group. Aβ, amyloid-β; I_A, transient outward potassium current
