- Figure 1.
Behavioral task and group performance data. A, Temporal motor sequence task. The learned sequence, visually presented stimuli, and response method are shown. B, Performance data from the TMST. PCOR and PSYN are shown across blocks. Group means for each measure are plotted for each day (d) and block (b): ET are shown in red, LT in blue, and NM in black. Error bars depict ±SEM. The vertical dotted line between d1b3 and d2b1 denotes the boundary between days of training.

ET versus LT group FA differences and extractions. A, ET > LT group difference in skeletonized FA (blue) in posterior midbody of the corpus callosum. The tract based on this seed connects the right and left sensorimotor cortices and is represented as the red-yellow underlay (where red represents a threshold of 1–10% of maximum particle count and bright yellow depicts 10% and greater). B, FA (top) and RD (bottom) values from the peak CC voxel plotted against group, age of onset, and PSYN Final. Values for ET are depicted in red, LT in blue, and NM in black. Group means are depicted with filled circles. Raw values were used for all plots while statistics were based on the corrected values as stated in the text. **p < 0.001.
- Figure 3.
Correlation between FA and age of onset of musical training. FA was significantly correlated with age of onset of musical training across musicians in bilateral rostral body and midbody of the corpus callosum (red). This region overlaps with the more posterior midbody location identified in the group contrast between ET and LT (overlayed in semitransparent blue visible in the top left and bottom right slices).
- Figure 4.
Whole-brain FA correlations with PSYN Final. A, Skeleton voxels significantly correlated with PSYN Final in left temporal lobe and posterior limb of the internal and external capsules (blue). B, Mean values extracted from the region of significant correlation plotted against group, age of onset, and PSYN Final. ET are shown in red, LT in blue, and NM in black. Group means are depicted with filled circles. Note that raw values were used for all plots while statistics were based on the corrected values as stated in the text. *p < 0.05.
