Summary of main effects and direct comparisons
While activation in the right anterior cerebellum sustained from the early to late stage
of visual setting, the activity decreased by the late stage in the motor setting. Whereas
the activation in the left dorsal putamen extended into both anterior and posterior
regions in the visual setting, that in the motor setting was found to be concentrated
within the posterior region. Further, activation in the putamen became stronger from
early to late stage in the visual setting, but it decreased by the late stage in motor
setting. Activation in the ventral striatum and hippocampus was found only in the
visual setting. There seems to be a trend of shift in activation from the parietal in early
visual to parietal-premotor areas in late visual and early motor settings. The activation
in premotor areas became stronger by the late stage of motor setting. The pre-SMA
was active only in the late stage of visual setting and the caudal SMA only in the late
stage of motor setting.
