Summary of Cohen’s D for measured values before and after loss of response (LOR).

EEG measure	Cohen’s D
1/fα fit	0.68
SampEn	-0.55
ERR	-0.69
Delta	-0.20
Theta	0.15
Alpha	0.61
Beta	0.34
Gamma	-0.55

We calculated Cohen’s D (sign convention: post-pre) to quantify the effect sizes of our EEG measures. We included all measures that showed significant differences before and after LOR, and the standard frequency bands for comparison. ERR value shown here is for the 4 ms delay.
