Graphical Summary of Results from Final Regression Model.
<p>The predicted <i>d’</i> values from the final model (the model containing local efficiency during task, global efficiency during task, age group, average RT, and an interaction between global efficiency during task and age group as parameters) are plotted against observed local efficiency (A) and global efficiency (B) values during the 2-back task, respectively, and split by age group.</p

Templates for the Central Executive Network and Default Mode Network.
<p>The central executive network template (red) included bilateral portions of the dorsal lateral prefrontal cortex, superior medial frontal cortex, and the superior parietal cortex. The default mode network template (blue) included bilateral portions of the medial prefrontal cortex, posterior cingulate cortex, precuneus, and inferior parietal cortex (MNI z-coordinates: CEN = 46mm, DMN = 34mm). These templates were used in the SI analysis of community structure.</p

Default Mode Network Community Consistency in Younger and Older Drinkers.
<p>Spatial consistency of these communities was assessed using the scaled inclusivity (SI) metric. Maximum spatial overlap of these communities (higher SI values) was represented as warmer colors and minimum overlap represented by cooler colors. Default Mode Network community consistency was significantly higher in younger adults at rest, but did not differ by age group during task (MNI z-coordinate = 33mm).</p
Default Mode Network Community Consistency in Light and Moderate-Heavy Drinkers.
<p>Spatial consistency of these communities was assessed using the scaled inclusivity (SI) metric. Maximum spatial overlap of these communities (higher SI values) was represented as warmer colors and minimum overlap represented by cooler colors. Default Mode Network community consistency was similar between light and moderate-heavy drinkers. Results pointed to decreased consistency in moderate-heavy drinkers compared to light drinkers, but the differences did not achieve significance (MNI z-coordinate = 33mm).</p
