Figure 9.

Replication of somatomotor topography projected onto a flatmap. Winner-take-all maps of active movements are displayed for four body parts along the anterior-posterior body axis projected onto flatmaps using the SUIT toolbox: tongue (red), right and left hands (yellow), glutes (green), and right and left feet (blue). Each panel displays a separate participant from the Replication sample (S5–S8). In participants S5–S7, the primary and secondary somatomotor maps are apparent in the anterior and posterior lobes of each hemisphere corresponding to the anterior-posterior body axis, with S6 and S7 showing the clearest examples. The experiment largely failed in S8 (the primary map is apparent but the secondary map is ambiguous). Also note the medial representations within the vermis of S5–S7. These may be hints for the hypothesized tertiary body representation in the cerebellum. Dotted lines indicate approximate lobule boundaries with lobules labeled for S5. A, anterior; L, left; P, posterior, R, right.
