Example wave forms. A: quality HFOs (qHFOs). B: HFOs detected using the Staba detector with common average reference, but rejected as they were coincident with artifact detections. Note, the horizontal scale is consistent within a given panel (A or B), but varies across panels. The vertical scale is consistent for panel A and subpanels B3-B5, and is separately consistent for subpanels B1-B2. Redacted false-positive HFO detections include fast DC shifts (B1, B3), fast transients (B2, B4) and data with very slow signal no noise ratio (B5).
