Figure 3. Grand-averaged event-related potentials (ERP) waveforms at five sites (Fz, Cz, Pz, C3, and C4) between the pre-heating baseline (1^st session, Rest) and during whole body cooling (4^th session, WBC) in Go trials (Panel A, upper figures) and No-go trials (Panel B, lower figures).

Blue and green lines show waveforms in the 1^st and 4^th sessions, respectively. The amplitudes of the P300 component in the Go trials are similar between the pre-heat baseline (1^st session, Rest) and recovery (4^th session, WBC), except for Pz, whereas those in the No-go trials remain smaller during WBC than during Rest.
