Figure 1. Meth significantly enhanced the outward K+ currents.

Figure 1

The microglial cells were incubated with Meth (100 µM) for 24 h, then the K+ currents were recorded in (A) control group. (B) Meth treated group. (C) MgTx application before recording in Meth treated group. (D) The I–V plots of the K+ current density of microglial cells activated by voltage steps increments from a holding potential of −70 mV with intervals from −70 mV to +30 mV during 500 ms. *p<0.05 compared with control group (n = 10–15).
