PNH subjects with active epilepsy are numbered as in Table 1. C1-C5 represent the matched healthy controls for subjects 1-5, respectively. Columns 2, 3, and 5 show the maximum amplitudes of the largest peak evoked by stimulation of the connected target in each of the three time periods, for the PNH subjects and their matched controls. Columns 4 and 6 show the ratios of the maximum amplitudes during the late versus early time periods.
