White matter microstructure is related to onset latency. a, Left hemisphere MD values within anatomically defined ROIs show a significant correlation: shorter latencies were related to greater MD values. b, White matter ROIs underlying auditory cortex on a single example subject overlaid on a T1-weighted anatomical image for illustrative purposes. c, Similar analyses on the right side did not show any significant correlation. This analysis was performed only in the speech condition because onset latencies to the natural piano tone were more variable (see Materials and Methods and Results for details).
