In the first study to use imaging technology to see what goes on in the brain when we scratch, researchers at Wake Forest University Baptist Medical Center have uncovered new clues about why scratching may be so relieving "“ and why it can be hard to stop. The work is reported online in the Journal of Investigative Dermatology and will appear in a future print issue. "Our study shows for the first time how scratching may relieve itch," said lead author Gil Yosipovitch, M.D., a...

The area of the brain that controls whether you keep rooting around the refrigerator or actually start chowing down has now been discovered. This brain region — which seems to help govern the "eureka" moment or turning point between exploration and mulling over one's discovery — is also linked to urges that malfunction in addiction and certain mental disorders, scientists added. The scientists presented two rhesus monkeys with a choice of four targets on a computer...

MADISON -- The mere mention of a stressful word like "wheeze" can activate two brain regions in asthmatics during an attack, and this brain activity may be associated with more severe asthma symptoms, according to a study by University of Wisconsin-Madison researchers and collaborators. The study, which appears in the Proceedings of the National Academy of Sciences (Online, August 29, 2005), reveals a functional link between emotion processing centers in the brain and certain physiological...

NEW YORK -- Psychological stress has been shown to have an effect on asthma flare-ups, and now the brain regions that appear to be responsible for this interaction have been identified, according to US researchers. As reported in the Proceedings of the National Academy of Sciences, Dr. Richard J. Davidson, from the University of Wisconsin at Madison, and colleagues used functional MRI -- that is, MRI scans that show activity as well as anatomical structures -- to determine the brain regions...

Deciphering the subtle, complex electrical signals emanating from the brain has yielded important insights into the still-mysterious neural mechanisms that underlie behavior. By recording a subject's faint brain signals via arrays of scalp electrodes during cognitive tasks, researchers can extract "event-related potentials" (ERPs) that enable them to pinpoint with great accuracy when the brain reacts to components of the tasks. One such intriguing ERP signal, called "error-related...
