Group categorical comparisons for circular vection (CV) vs. random dot stimulation. Results of the group subtraction analysis of CV vs. random dot movement in 14 volunteers, showing the most significant activation in the midline structures of the cerebellum, i.e., the declive and folium of the cerebellar vermis, as well as parts of the tonsil and pyramid (upper and middle row). The activation cluster is projected onto a standard template provided by SPM in three different views (C = coronary, S = sagittal, T = transverse). At cortical level (lower row) signal differences were found in the superior parietal lobule/precuneus bilaterally (LPs/PCu, BA 7), the right medial frontal gyrus (GFm, BA 8/9, frontal eye field), the right anterior cingulate gyrus (GC, BA 24/31/32), and the right postcentral region (GPoC, BA 3).
