Bridging cognition and action: executive functioning mediates the relationship between white matter fiber density and complex motor abilities in older adults

class="figure-viewer-img"

Figure 2. Relationships between prefrontal fiber density, executive functioning performance, and motor performance in older adults. Scatter plot and the best least square line for (A) executive functioning and (B) motor performance association with prefrontal fiber density, after accounting for the estimated total intracranial volume (TIV), are shown. Partial Pearson’s coefficients and the Bonferroni-corrected p-values are indicated. (C) Executive functioning performance mediates the relationship between prefrontal fiber density and complex motor performance in older adults. * p < 0.01.
