Working memory training (dual n-back) improves white matter tract integrity: White matter matters

White matter matters.  Yes, my readers may be tiring of this common mantra.

But, another new study has again implicated the importance of white matter integrity.  More importantly, the study suggests that a working memory training program (dual n-back) may be effective in increasing white matter integrity, thus increasing the efficiency and synchronization of communication between different brain networks.  Click on the images below to enlarge.

This study is consistent with my hypothesis that the effectiveness of some brain training programs may be due to increased white matter tract integrity.  An explanation, with a link to a MindHub pub white paper outlining this hypothesis, can be found here.  Other white matter related posts can be found here.
