Measured cTMS waveforms for PWs of tp = 20, 40, 60, 80, 100, and 120 μs: (a) IGBT collector voltage VC2; (b) coil current IL; (c) search coil voltage Vs proportional to induced electric field by TMS coil; (d) low-pass filtered search coil voltage Vf proportional to neuronal membrane potential for membrane time constant of 150 μs.
