Supplementary Figure 4: Example hippocampal EEG traces illustrating multi-event SOs along with nested spindles.

Top: Unfiltered raw EEG traces, highlighting data segments identified as a SO (green) and spindle (blue) by our automated algorithm. Bottom: Same data segments after applying the event-specific bandpass filters (SO: 0.5–1.25 Hz, spindle: 12–16 Hz).
