Researchers in France used PET imaging to evaluate metabolic activity in brain tissues of older adults showing no signs of amyloid accumulation plus functional MRI to assess neural activity and functional connectivity. The study, published in NeuroImage, found that gray matter volume was linked to the number of years of education the patients had. The researchers observed greater volume in three brain regions -- the right superior temporal gyrus, anterior cingulate gyrus and left insular cortex -- along with functional changes tied to level of education.
