Figure 3.

Group mean time course of the BOLD signal for motor, early-onset, and late-onset regions. The black arrows point to frame 3, which showed a significantly higher signal in early-target hit trials than in late-target hit or no-target correct rejection trials. The gray arrows point to frame 5, which showed a significantly smaller signal in early-target hit trials than in late-target hit or no-target correct rejection trials. Cs, central sulcus; PostCg, postcentral gyrus; ant IPs, anterior intraparietal sulcus; lat occ, lateral occipital; med, medial; MFg, middle frontal gyrus; SPL, superior parietal lobule; pos, posterior.
