A new study in the Journal of Neuroscience reports that significant reductions in cortical volume occur during normal aging over the span of only one year. The researchers collected MRI data from 142 healthy elderly people aged 60-91 (60 is elderly? Really?). Cortical volume reduction was detectable in several regions, but most prominently in temporal and prefrontal cortices which of course includes regions involved in language function. No wonder I can't remember names anymore...
