Hierarchal Linear Regressions in a priori regions of interest using linear and quadratic age. Bilateral dorsal and ventral lateral prefrontal cortex regions of interest defined by 8 mm sphere around the peak within that region from the Label > Blur contrast (at p < 0.0001, k ≥ 14). Medial orbital frontal cortex and bilateral amygdala regions of interest defined by 8 mm sphere around the peak within that region from the View > Blur contrast (at p < 0.0001, k ≥ 14).
