The y axis indicates the mean across time of the cognitive matching score (n = 15 human volunteers). In the box plots, the central lines indicate median values, the bounds of the boxes indicate the 25th and 75th percentiles, the whiskers indicate 1.5x the interquartile range and extreme values are shown as individual circles. P values were obtained from repeated-measures t -tests (two sided) and false discovery rate corrected for multiple comparisons. Significance values for comparisons with the awake data are shown in black and those for comparisons versus the recovery data are shown in grey. See Supplementary Data 1 for full statistical reporting. Source data are provided. Avg, average; supp, suppression.
