Figure 3.

Effects of dmLSB on the whole-cell current. (a) Current responses to step voltage pulses (inset, −120 to +80 mV) from V_h of −80 mV were recorded in whole-cell mode using K⁺-rich pipette solution. Left: control condition; right: in the presence of 10 μM dmLSB. (b) Voltage dependence of current amplitude measured at 20 ms (left) and at 950 ms (right) of the step pulses. The I–V relationships before (open circle) and after (closed circle) the dmLSB application were superimposed in each plot.
