Ed, back up for a minute - are you saying that as a result of the literacy training, the grey matter in the adult sample increased (you wrote: "had more grey matter in five regions towards the back of their brains") as in somehow added more neuronal cell bodies, neuropil, etc.    From Wordnik.com.  [Literacy News – 65th Edition « News « Literacy News] Reference

The neuropil was shrunken in these regions, and the ventricles had correspondingly expanded to fill the space.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

CTE is characterized by the build-up of a toxic protein called tau in the form of neurofibrillary tangles (NFTs) and neuropil threads (NTs) throughout the brain.    From Wordnik.com.  [THE MEDICAL NEWS] Reference

Hence, we show that E2 transiently increases neuronal connectivity by inducing dynamic nascent spines that "sample" the surrounding neuropil and that subsequent NMDAR activity is sufficient to stabilize or "hold" E2-mediated effects.    From Wordnik.com.  [Proceedings of the National Academy of Sciences current issue] Reference
