Figure 8

Wavelet analysis of channel RHD4 for the recording for Patient 1, Seizure 1. The inverse filtered reconstruction (orange trace) shows a large low frequency component at seizure onset that is not apparent in the raw recording (black trace) (A). Time–frequency analysis confirmed that frequencies below 0.1 Hz are severely attenuated in the raw recording (B) but restored in the reconstruction (C). The vertical dotted lines indicate seizure onset and offset.
