Neuroscientifically Challenged
Neuroscience made simpler.
The brain, explained — reference entries and stories, written and reviewed by people who study it.
In focus
Walking into a room and forgetting why you came isn’t a sign your memory is failing, because Notre Dame researchers found that simply passing through a doorway makes people forget more, as the brain closes the file on one scene and opens a new one for the next
A Scottish nurse told scientists she could smell Parkinson's on people, so they gave her 12 worn T-shirts to sniff, and she picked out every patient; the one healthy man she refused to clear was diagnosed months later
