Cognitive Intraindividual Variability and White Matter Integrity in Aging
Figure 1
Radiological convention—right of the subject on the left of the figure. (a) Young > old: map of regions significantly more activated (in red) by the young population than by the older population in the RT task (CrossSquare). The right prefrontal (superior frontal gyrus) region is activated in the younger adults, as well as the angular gyrus (right more than left). (b) Old > young: map of regions significantly more activated (in red) by the old population than by the younger population in the RT task. There is significantly more right insular activation in the older population, as well as some larger bifrontal, supplementary motor areas and parietal networks (perirolandic).
