New, ultra-high-field magnetic resonance images (MRI) of the brain by researchers at the University of Illinois provide the most detailed images to date to show that while the brain shrinks with age, brain cell density remains constant. The study, of cognitively normal young and old adults, is published in the journal NMR in Biomedicine. In the current study the images were made by a powerful … Continue reading First evidence provided that in normal aging cell density is preserved throughout the human brain.
