Figure 12. In-strength index computed for π node of the physiological network.

Box plots report the distribution across subjects (median: red lines; interquartile range: box; 10^th−90^th percentiles: blue bars) and the individual values (circles) of the in-strength computed at rest (R), during mental stress (M) and during serious game (G). Statistically significant differences between pairs of distributions are marked with # (R vs G).
