Fig. 5: Changes in the preferred direction of PMdr, PMdc, and M1.
a Pseudo-color maps of PDI in early and late sessions for marmosets 1–3. Pixels with cvR2 of <0.02 in both pull and push trials were not analyzed. b Histograms of the PDI (bars) of pixels in early (left) and late (right) sessions in PMdr (top, n = 348 pixels in both early and late sessions), PMdc (middle, n = 534 pixels in both early and late sessions), and M1 (bottom, n = 942 pixels in both early and late sessions) in marmosets 1–3. The cvR2 averaged within each bin for pull (red) and push (blue) trials is overlaid. The cvR2 is presented as mean ± SEM. White boxes indicate the fraction of the pixels with significant PDIs (P < 0.05, permutation test, one-sided) and gray boxes indicate the fraction of the others. c PDI of PMdr, PMdc, and M1 in early and late sessions for marmosets 1–3. Black lines indicate the area-averaged PDI of individual datasets. The numbers of pixels in the datasets are indicated at the bottom. *P < 0.05, Wilcoxon signed-rank test, two-sided. d Histograms of ΔPDIEL of PMdr (green), PMdc (brown), and M1 (red) in marmosets 1–3. The green, brown, and red triangles indicate the median of the PDI distribution of PMdr, PMdc, and M1, respectively. *P < 0.05, Wilcoxon signed-rank test, two-sided. Source data are provided as the Source Data file.
