Fig 6. Scatterplots of fiber number, tract volume, and median MR imaging parameters across the whole-brain portions of the left versus right CSTs. Cross-scan means (squares) and 95% confidence intervals of the mean (error bars) are shown only for individuals who were scanned several times. In each plot, the 99% normal range derived from all healthy individuals (including those scanned only once) is shaded gray. Note that only the normal range is shown for T1 because we did not obtain absolute T1 data on multiple occasions from any individual.
