3A). Additional regions, namely the left inferior occipital gyrus (BA 19), right middle temporal/fusiform gyrus (BA 37) and the bilateral superior and left superior temporal gyrus (BA 20, 41, 42), were more strongly activated in the dynamic task (for details see Table 1A). During

AO, no differences between activity in the dynamic and static tasks were detected in the SMA, basal ganglia or cerebellum (Fig. 3B); however, significant task difference for other brain regions were evident in AO (see Table 1B). No significant differences between activity on the dynamic and static tasks were seen in the MI condition, although simple effects analysis indicated that the SMA and cerebellum were more strongly activated in the dynamic task (Fig. 2). AO + MI

of the dynamic task resulted in greater activity in SMA, basal ganglia (putamen and caudate), and cerebellum than AO (contrast: AO + MI > AO) (Fig. 4). In selleck products addition, during AO + MI there was significant activity in the precentral gyrus, particularly in PMv, but also in PMd. In both regions activation was more pronounced in the left hemisphere. The ROI analysis for M1 showed greater activity on the left side during AO + MI than during AO (p = .045). Several other regions including the left superior and right inferior frontal gyrus (BA 9), the inferior parietal lobule (BA 40), insula (BA selleck compound 13) and thalamus, displayed greater activity during AO + MI than AO (for details see Table 2). Similar, but weaker effects were found for AO + MI versus AO of the static task: the SMA, basal ganglia, right cerebellum and premotor cortices (PMv and PMd) were more strongly activated during AO + MI than AO (not illustrated due to space limitations). For Galeterone the inverse contrasts (AO vs AO + MI; dynamic and static), there were no significant findings. The contrast between AO + MI and MI (AO + MI > MI) on

the dynamic task revealed greater bilateral activity in the cerebellum during AO + MI (Fig. 5). The ROI analysis for M1 showed greater bilateral activity during AO + MI than MI (p = .004 for the right and p = .016 for the left). In addition, visual centers such as the inferior and middle occipital gyrus (BA 18, 19) and fusiform gyrus (BA 19, 37) were recruited during AO + MI. Furthermore, the precuneus showed greater activation during the AO + MI condition than the MI condition. On the static balance task, the same comparison shows that cerebellar activity was again more pronounced in the AO + MI condition than in the MI condition (not illustrated due to space limitations). Finally, the inverse contrasts (MI > AO) did not show significant differences for dynamic and static task, respectively. A comparison between brain activity in the MI and AO conditions (MI > AO) during the dynamic task revealed greater activity in the SMA, left precentral gyrus (BA 44), right insula (BA 13), left middle frontal gyrus (BA 9), and left thalamus.
