For the first time, scientists at Carnegie Mellon University have identified which emotion a person is experiencing based on brain activity.

Pre-treatment scans of brain activity predicted whether depressed patients would best achieve remission with an antidepressant medication or psychotherapy, in a new study.

People who experience any stroke symptoms—but do not have a stroke—may also be more likely to develop problems with memory and thinking, according to new research published in the June 19, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

And finally this week, a study, led by Royal Holloway University researcher Carolyn McGettigan, has identified the brain regions and interactions involved in impersonations and accents.
