Figure 4. Persistent TMS-evoked activity in a patient with PNH and active epilepsy, but with a normal interictal EEG.

Figure 4

A. The TMS-evoked response produced by stimulation of the connected target site in subject 1. B. The TMS-evoked response produced by stimulation of the same site in the matched healthy control subject. The later peaks (>225 ms) in the PNH subject are of the same size as or larger than earlier peaks, whereas the later peaks are smaller than the earlier peaks in the matched healthy control subject. Notably, subject 1 had entirely normal interictal findings on prolonged continuous EEG monitoring. Note that the evoked potentials are not plotted on a uniform scale.
