Task design. In the free-timing condition, each subject freely decided when to move his right hand while fixating his gaze on a stationary mark. In the cued timing condition, the subject produced movements in response to a visual cue.

fMRI signal time courses. The red line represents the time of movement onset, defined as T = 0 (s). The shaded region indicates the time window (−4 ≤ T ≤ 1) in which the fMRI responses in the free-timing and cued-timing conditions were compared, and asterisks indicate statistically significant differences (p < 0.05). Even absent an external stimulus, significant buildups of activation during the premovement period were observed in the visual cortex, auditory cortex, SMA, precuneus, right IPL, right IFG, and insula.

Subtraction t-maps during premovement period. Subtraction t-maps (free timing minus cued timing) showed neural activities in multiple cortical areas, beginning several seconds before the onset of self-initiated movement, defined as T = 0. AUD, auditory cortex; INS, insula; Pcu, precuneus; VIS, visual cortex; L, left; R, right.
