Fig. 3
Time course of pupillary diameter variations as a function of stimulus category in healthy volunteers (HV), minimally conscious state patients and vegetative state/unresponsive wakefulness syndrome patients. Mean values and standard deviations are shown from − 500 ms to 3000 ms after stimulus presentation. Intervals during which pupillary variations induced by the presentation of sun photographs differed from those induced by other categories are marked by lines in the corresponding category’s color compared to the sun. Permutation test corrected for multiple comparisons over time using FDR (p < 0.05).
