Figure 1. — Panel A shows a 275 channel CTF Omega MEG system. Panel (B) shows the subject specific head-cast. The head-cast fits the subject internally and the MEG system externally. Panel (C) shows the configuration of the stimulation coils within the pT helmet device. The view here is from below showing the five coil groups: vertex, left temporal, right temporal, occipital and frontal coils (at top of picture). Panel (D) shows a schematic of the pT square-wave stimulation waveform as a function of time.
