Functional expression of ChR2 in C2C12 myotubes investigated by patch-clamp. (A) Inward ChR2 current recorded at a holding potential of −50 mV during a light pulse of 4 ms at various light intensities. Light pulse is schematized as a blue rectangle. (B) ChR2 current recorded as described in A represented as percentage of maximum ChR2 current recorded at 4.3 mW.mm−2. Data are expressed as mean ± SEM (n = 6).
