Supplementary Figure 7: Example hippocampal EEG traces containing a SO-spindle-ripple interaction.

From: Hierarchical nesting of slow oscillations, spindles and ripples in the human hippocampus during sleep

Supplementary Figure 7

Top: Unfiltered raw EEG traces, highlighting data segments identified as a SO (green), spindle (blue) and ripple (red) 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, ripple: 80–100 Hz). Insets zoom in on the ripple event, highlighting its oscillatory nature and its nesting in spindle troughs.
