Figure 17.

Relative location of hand and foot representations in the candidate tertiary map. The three columns display sections in sagittal (left), coronal (middle), and transverse (right) orientation. Right versus left contrasts show hand and foot primary (H₁, F₁), secondary (H₂, F₂), and tertiary (H₃, F₃) representations. Note that the tertiary hand representation is superior and lateral to the foot. It is unclear what the definitive orientation of the tertiary body map is since the secondary and tertiary hand representations appear here as continuous. Nonetheless, these data are consistent with an upright map. The anatomical backdrop is the average volume from the eight participants contributing to the functional data. In the middle and right columns, left is displayed on the left. Coordinates at the bottom right of each panel indicate the section level in the space of the MNI152 atlas. The color bar represents the mean β values. A, anterior; I, inferior; L, left; P, posterior; R, right; S, superior.
