Pupillary unrest (PUI and SampEn)
The main effect of drug on PUI was significant, Profile of two pupil size measures after IN-OT: PUI and SampEn; in a resting-state paradigm. Significant pairwise comparisons (IN-OT vs placebo) at specific time windows are marked with an asterisk (*). Time windows: 1 = 20–25 min; 2 = 35–40 min; 3 = 50–55 min; 4 = 65–70 min; 5 = 80–85 min; and 6 = 95–100 min. Error bars: Standard error. PUI: pupillary unrest index; SampEn: sample entropy; IN-OT: intranasal oxytocin.
