From accidentally deleting a computer file to dropping something, we all make mistakes -- and now Michigan scientists are learning how that affects the brain.
University of Michigan researchers used an imaging scan to view the human brain the instant a costly mistake occurs. What they've found might help scientists better understand mental health problems.
The scientists found the brain's rostral anterior cingulate cortex, or rACC, becomes much more active when a person realizes making an error of some consequence. By contrast, the same area doesn't show the same activity when the mistake is minor or doesn't carry a penalty,
The rACC is thought to be involved with emotional responses, and scientists had suspected it might also be involved in response to costly errors. But this is the first brain-imaging study to test that idea.
"In general, the response to a mistake that cost ... money was greater than the response to other mistakes, and the involvement of the rACC suggests the importance of emotions in decision and performance-monitoring processes," said Dr. Stephan Taylor, an associate professor of psychiatry and lead author of the research.
The research is published in the Journal of Neuroscience.

Better understanding of signaling pathway to lead to new therapies
Researchers have found the first direct proof that a key protein drives the clogging of arteries in two ways, and that lowering levels of it opens them up, according to study results published in the June edition of the journal
Circulation. The work establishes cyclophilin A as an exciting target in the design of drugs against atherosclerosis, the number one cause of heart attacks and strokes, which occur when vessels become completely blocked. While the study was in mice, higher levels of the study protein have also been found in the blood of human patients with diseased blood vessels.

Rare genetic syndrome may hold key to cure for heat stroke
A genetic disorder that can cause a fatal rise in body temperature in some patients undergoing general anesthesia may hold the key to a cure for heat stroke, according to research published in the April 4 edition of the journal
Cell. The findings further suggest that antioxidants, like those currently being tested to protect the lungs of cystic fibrosis patients, may also protect those genetically prone to suffer heat stroke.
New breed of cognitive robot... a puppy?
Designers of artificial cognitive systems have tended to adopt one of two approaches to building robots that can think for themselves: classical rule-based artificial intelligence or artificial neural networks. Both have advantages and disadvantages, and combining the two offers the best of both worlds, say a team of European researchers who have developed a new breed of cognitive, learning robot that goes beyond the state of the art.
Why we learn from our mistakes
Psychologists from the University of Exeter have identified an 'early warning signal' in the brain that helps us avoid repeating previous mistakes. Published in the
Journal of Cognitive Neuroscience, their research identifies, for the first time, a mechanism in the brain that reacts in just 0.1 seconds to things that have resulted in us making errors in the past.
Microsoft-Yahoo: Which Products Would Win
While the chance of a Microsoft-Yahoo merger or acquisition is a remote one, it's still a possibility. In analysis compiled from several PC Magazine staff members and analysts, here's what a merger might mean to the products and technologies directly shared by each company. In each case, we've outlined the strengths and weaknesses of each, and attempted to predict what technologies would survive the backroom planning sessions, and what would be discarded.
