Individual data plotted on top of group averages. a Time course of salivary cortisol concentration (nmol/L). B1 and B2, Baseline 1 and 2. MRS, MR spectroscopy. The red box represents the control/stress intervention (~T0). In the SCR group, cortisol levels were significantly elevated at the start of MSL (T25; 25 min post stress intervention) and remained elevated until 60 min post intervention (T60). Cortisol of two subjects at B1 (1 control, 1 SCR) were missing. See Supplementary Results section 2.2 (and corresponding Supplementary Fig. 2c) for results of the analysis of the time course of cortisol concentration in the stress and control groups before cortisol responder/non-responder classification. (*) Indicates significant group differences at pcorr < 0.05. b Performance speed (inter-response interval between consecutive correct key presses, IRI) plotted as a function of blocks of practice during MSL for the control and SCR groups. Performance speed improved with practice and to a similar rate in both groups. Error bars in all panels represent SEM.
