Microstate parameters before and after the loss of responsiveness in drowsiness. Within each panel of grouped scatter box plots, inner boxes represent the standard error of the mean for each microstate parameter, and outer boxes represent the standard deviation. The mean is shown by a continuous line, the median is shown by a dotted line, and individual participants are shown as dots. Asterisks show a significant within-subject main effect of state for a microstate. Duration, temporal coverage and GEV of microstate D all significantly increased during unresponsiveness
