In an unlikely pairing, two professional rappers have teamed up with researchers from the National Institutes of Health to study what happens in the brain during freestyle rapping. The results, published Thursday in the journal Scientific Reports , suggest that the process is similar to that of other spontaneous creative acts, including jazz improvisation. The study was initiated by the Los Angeles-based rappers Daniel Rizik-Baer and Michael Eagle and carried out by Allen Braun and Siyuan Liu of the NIH's National Institute on Deafness and Other Communication Disorders.

A yearlong study of boxers' and mixed martial-arts fighters' brain activity has found those who fight for more than six years begin to experience damage and those who fight longer than 12 years expose themselves to an even greater decline each time they return to the ring. "What we've found suggests changes and damage in the brain happens years before symptoms emerge," said Dr. Charles Bernick, author of the study. "It's what we see in Alzheimer's and Parkinson's patients. " Bernick has supervised MRIs and computerized and cognitive tests of an estimated 170 fighters at the Cleveland Clinic's Las Vegas center in the past year.

In some ways, parties seem like the worst possible places to socialize. A cacophony of voices -- not to mention a blaring stereo system -- make for a noisy environment in which to hear what a friend is saying. Hence the term "the cocktail-party effect," which refers to people's ability to focus on one speaker and tune out another. Now Nima Mesgarani and Edward F. Chang of UC San Francisco have figured out how the brain accomplishes this feat of selective hearing: The auditory cortex, which processes sounds, favors the voice that it needs or wants to hear.

A UC Irvine scientist has won a $165,000 grant to help develop a revolutionary technique for mapping brain activity, university officials announced. Ron Frostig, an assistant professor of psychobiology at UCI, received the award recently from the Arnold and Mabel Beckman Foundation. He plans to use the funds to continue research into the way various parts of the brain reflect light.

Imprisoned financier Michele Sindona, who was once known as "God's Banker" because of his ties with the Vatican, was reported in a deep coma and near death, two days after being sentenced to a life term for ordering a murder. Sindona, 65, was taken ill as he ate breakfast at a prison in Voghera, Italy. He was reported to have been in a coma on arrival at a nearby hospital, where tests indicated no brain activity.

Could the teen brain identify chart-topping pop music hits -- and duds -- before a big-shot producer ever could? Perhaps, according to a study published online June 8 in the Journal of Consumer Psychology. Almost by accident, some previous research by Emory University scientists into the teen brain showed that adolescents' brain activity could potentially predict a song's ultimate success or failure. Back in 2006, Emory University neuroeconomist Gregory Berns had 27 teens between age 12 and 17 listen to 120 songs picked from Myspace that were relatively unknown artists without recording contracts, and measured the teens' brain activity.

How does the formidable human brain organize its memories? A new study used electrical activity of the brain to investigate. The resulting report shows that when people think of words that are linked by their meanings -- "apple" and "orange," for example -- the brain often exhibits similar patterns of activity. There's a futuristic, Big Brother-ish dimension to the work: The authors argue that down the road, their results might be useful in mind-reading approaches that rely on connecting measurements of brain activity to what a person is thinking.

An early symptom of autism might be found in a baby's gaze, researchers reported Thursday. Diagnosing autism as early as possible is of critical importance. Studies show the earlier therapy begins, the more likely the child can overcome the deficits linked to the brain disorder. The new study, published online in the journal Current Biology , examined babies 6 months to 10 months of age who were at higher risk of developing autism because they had an older sibling with autism.
