Experimental procedure (Days 2 and 3). Each evaluation period (p1, p2, and p3) comprises (1) visual analog scales for fatigue (VASf) and sleepiness (VASs), (2) a 4-min resting state (Rst) period, (3) a 5-min version of the psychomotor vigilance task (PVT) and (4) again the VASf and VASs. After the evaluation period p1, the CF-inducing TloadDback was administered for 16 min, immediately followed by the second evaluation period (p2). The third evaluation period (p3) was then administered after a 16-min break (recovery time). Brain activity was recorded using fNIRS during the 3 evaluation periods and the TloadDback task. Additionally, eyeblink and yawns were video recorded during the resting state sessions. tDCS (sham or real, in counterbalanced order) was applied for 25 min starting from the beginning of the experiment.
