Older brains may be more similar to younger brains than previously thought.

In a new paper published in Human Brain Mapping, BBSRC-funded researchers at the University of Cambridge and Medical Research Council's Cognition and Brain Sciences Unit demonstrate that previously reported changes in the ageing brain using functional magnetic resonance imaging (fMRI) may be due to vascular (or blood vessels) changes, rather than changes in neuronal activity itself.
