Changes in connectivity with age.
The weight, or contribution, of each target region in the final model of age by amygdala connectivity, are displayed. Negative weights represent decreasing connectivity with age, and range from dark-blue (corresponding to lower absolute weights in the model) to light-blue (higher absolute weights). Positive weights (increasing connectivity with age) are illustrated by the red- (low weights) to-yellow (high weights) colors. Right and left amygdalae are depicted in purple.
