Brain regions associated with step length variability. Top panels show the areas identified by the mean cortical thickness and the bottom panels show the areas identified by cortical thickness ratio; color scale corresponds to log of one-sided Bayes factors; regions of cool colors indicate smaller thickness or ratio associated with greater variability; regions of warmer colors indicate greater thickness or ratio associated with greater variability. Only the regions with credibility intervals that do not cross zero are shown, A-P; Anterior-Posterior, RH; Right Hemisphere, LH; Left Hemisphere.
