Extended Data Fig. 7 — a) Example LFP recording from the sFL and skin brightness trace during QS, showing increases in neural activity at times of QS colour flashes. b) low-frequency (LF) (0.1-10 Hz) and high-frequency (HF) (20-150 Hz) activity across recording electrodes during QS. Colour scales as in Fig. 3e–h. c) Relationship between low-frequency LFP activity strength during waking and QS colour flashes. Crosses correspond to the mean ± 95% confidence interval for all electrodes located in a brain region. Colours denote brain regions, as in Extended Data Fig. 6. N = 583, 477, 85, 81, 84, 239, 395 electrodes from N = 8, 3, 3, 2, 3, 3, 6 animals for VL, sFL, iFL, Buc, Subr, dBL, Subv respectfully. d) As d) but for high-frequency LFP activity strength. e) Distributions of the magnitude of skin brightness change for AS bouts, QS colour flashes, and QS oscillation events. f) QS oscillation event inter-event interval distribution. g) Top: Example LFP recording (filtered 0.5-150 Hz for display) from the anterior VL during QS, showing detected QS oscillatory events (arrowheads). Bottom: Spectrogram of above VL LFP recording (normalised 0-1, Methods). h) Average spectrogram over QS oscillatory events detected in the anterior VL (N = 2111, single recording, colour scale as in h).
