Summary of spectral changes from before and after loss of response (LOR).

Frequency	Percentage	Percentage	Significance
band	of power	of power	value,
	PRE LOR	POST LOR	corrected
Delta (0.1–4 Hz)	76.3% [66.5, 83.7]	74.1% [60.1, 82.8]	0.22
Theta (4–8 Hz)	4.8% [3.2, 7.1]	6.4% [4.3, 9.4]	0.34
Alpha (8–14 Hz)	5.3% [3.2, 7.7]	8.7% [5.1, 15.0]	0.015∗
Beta (14–30 Hz)	3.8% [2.2, 5.3]	3.9% [2.8, 8.9]	0.26
Gamma (>30 Hz)	0.6% [0.4, 2.6]	0.4% [0.3, 0.6]	0.03∗

Percentage of power in individual frequency bands are reported as medians [25, 75 percentiles]. Significance values reported are from Wilcoxon signed rank tests, corrected for multiple comparisons. The ^∗ indicates the percentage of power change was significant at p < 0.05 corrected.
