Figure 3.

Transcranial magnetic stimulation (TMS)‐evoked potentials following single‐pulse TMS over left prefrontal cortex (F1 electrode) before the application of theta burst stimulation. Data were combined across three different stimulation conditions at baseline. (a) Butterfly plot of all electrodes with peaks of interest indicated in the text. The waveform in red line is formed using the average of three fronto‐central electrodes (FC1, FCz, FC2) for graphical representation of prefrontal activity. Topographical distribution of (b) voltage and (c) source activity (minimum norm estimates (MNEs)) at the level of cortex for each peak. “X” on topoplots indicate stimulation site (F1 electrode) [Color figure can be viewed at http://wileyonlinelibrary.com]
