Brain Activity

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 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.

Does depth perception develop in humans as a result of nature or nurture? It's a question scientists have wondered about. And a new study comes to a surprising conclusion: Babies acquire binocular vision as a result of viewing the world around them, not merely thanks to genetic programming. "My guess was that it was going to be something in between nature and nurture," said study leader Ilona Kovacs, a psychologist at the Budapest University of Technology and Economics in Hungary.

Fear is a complicated emotion, and scientists have recruited a scary laboratory aide ? the Brazilian salmon pink tarantula ? to help map out how the feeling is processed in the brain. Using video of the 8.7-inch-long arachnid, British researchers showed that the human brain engages several different systems when evaluating threats. For instance, the part of the brain that engages when a threat is approaching is different from the part that is activated when a threat is receding, they reported Monday in the journal Proceedings of the National Academy of Sciences.

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.

Anesthesia doesn't put patients to "sleep," as they're often told. Rather, anesthesia puts the brain into a state of unconsciousness that's more like being in a reversible coma than being asleep, a new study says. The study published in the New England Journal of Medicine on Thursday looked at how the brain behaves while asleep, in a coma and under general anesthesia. The brain activity of an anesthetized patient, for example, was more like a deeply unconscious coma patient than someone sleeping.

Researchers have moved one step closer to understanding how anesthesia drugs work by identifying a component of brain activity that could explain why we lose consciousness under the influence of the drugs, according to a study published Monday in the Proceedings of the National Academy of Sciences. Though "going under" is an extremely common part of many medical procedures, the mechanism by which it works remains a mystery. This fact has practical ramifications: Some studies have shown that anesthesia can lead to loss of memory and other side effects, something researchers might be able to alleviate if they understand exactly what the drugs do in the body.

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.
