...touring a retirement community with his mother and sister: "[W]e'd been given a tour by one of the facility's residents rather than by an employee...There we stumbled onto a scene that has been permanently imprinted on my brain: five limp, totally beleaguered residents - all women - were seated around a television set whose screen was pure snow; one of the women was clutching a doll whose single eye was a clothes button...
...break with tradition, Harvard awarded Senator Edward M. Kennedy ’54-’56, the liberal lion who has represented Massachusetts for nearly a half century and was diagnosed with brain tumor in May, with an honorary degree at a special ceremony in December. Though the University normally dispenses honorariums during Commencement, it delayed Kennedy's award because his medical treatment prevented him from appearing at the spring ceremony. The December event drew national press and political luminaries—including Vice President-elect Joseph R. Biden, Jr. and Mass. Senator John F. Kerry?...
...study by researchers at Vanderbilt University in Nashville and Albert Einstein College of Medicine in New York City suggests a biological explanation for why certain people tend to live life on the edge - it involves the neurotransmitter dopamine, the brain's feel-good chemical. (See the Year in Health, from...
Dopamine is responsible for making us feel satisfied after a filling meal, happy when our favorite football team wins, or really happy when we use stimulating drugs like amphetamines or cocaine, which can artificially squeeze more dopamine out of the nerve cells in our brain. It's also responsible for the high we feel when we do something daring, like skiing down a double black diamond slope or skydiving out of a plane. In the risk taker's brain, researchers report in the Journal of Neuroscience, there appear to be fewer dopamine-inhibiting receptors - meaning that daredevils' brains are more...
David Zald, a professor of psychology and psychiatry at Vanderbilt, studied whether the brains of those thrill seekers differed in any way from those of the less adventuresome when it comes to dopamine. He gave 34 men and women a questionnaire to assess their novelty-seeking tendencies, then scanned their brains using a technique called positron emission tomography to figure out how many dopamine receptors the participants had. Zald and his team were on the lookout for a particular dopamine-regulating receptor, which monitors levels of the neurotransmitter and signals brain cells to stop churning it out when there...
