neuroscience

A few weeks ago I was reading about a meta-study that looked for patterns in MRI data from multiple studies. They discovered something that explains a lot, IMHO. As brains age, the way they work changes. Young, healthy adult brains show activity in multiple areas when presented with new information. Multiple pathways connect across multiple areas literally thinking differently about the same thing at the same time. As brains age thinking becomes more distributed and monolithic.
