Univariate and multivariate content related to different actions performed with a given body part across S1 homunculus
(A) Univariate activity levels (versus rest) for the two actions (gray hatched, squeeze; black hatched, push) performed with each body part (green, feet; red, hand; blue, lips) within each ROI.
(B) Multivariate dissimilarities. The left plots are a MDS depiction of the representational dissimilarity between the two actions (gray ellipses, squeeze; black ellipses, push) performed with the non-primary body parts in each ROI (green, feet; red, hand; blue, lips). Ellipses indicate between-participant standard errors. The right histograms show the cross-validated dissimilarity (a.u.) observed for the two actions performed with each body part in each ROI (green, feet; red, hand; blue, lips).
Data are represented as mean ± SEM. Gray dots represent individual participants. ∗p < 0.017; #p < 0.033; ∗∗∗p < 0.001. See Figure S4 for similar analysis in the non-dominant hemisphere.
