Nobody fully understands how Ritalin and other stimulants work, nor do doctors have a very precise picture of the physiology of ADHD. Researchers generally suspect a defect in the frontal lobes of the brain, which regulate behavior. This region is rich in the neurotransmitters dopamine and norepinephrine, which are influenced by drugs like Ritalin. But the lack of a more specific explanation has led some psychologists to question whether ADHD is truly a disorder at all or merely a set of characteristics that tend to cluster together. Just because something responds to a drug doesn't mean...
ADHD researchers counter the skeptics by pointing to a growing body of biological clues. For instance, several studies have found that people with ADHD have decreased blood flow and lower levels of electrical activity in the frontal lobes than normal adults and children. In 1990 Dr. Alan Zametkin at the National Institute of Mental Health found that in PET scans, adults with ADD showed slightly lower rates of metabolism in areas of the brain's cortex known to be involved in the control of attention, impulses and motor activity...
...anointing Jones as "a conceptual artist with a head for business." One would like to drag semiology in here too, for the Slickers never saw a text they couldn't subvert. But Jones' tactic was not deconstruction so much as demolition. His long-touring Musical Depreciation Revue was a frontal assault on sonic propriety. Even his nickname was an action verb, pithily expressing what the man did to music. He drove it into the ground, he impaled it on a drumstick, he laced it with aural rotgut, he deleted it from all genteel associations. He spiked...
...celebrities in their midst. When Brad Fraser's Poor Super Man opened last week in Cincinnati, however, the TV- news crews and the theatergoers they accosted were talking about spectators so anonymous no one knew their faces. They were from the police vice squad, checking whether the show's frontal nudity, simulated oral and anal sex, and blunt language violated public decency. "A lot of people wanted to be at this performance," said Ensemble Theatre artistic director David White, "because they weren't sure there would be another...
...over campus. Unfortunately, there's this guy who reads his Crimson in the nude. I won't say what House this guy's in to spare him. This fellow is in one of my classes. Should I tell him that people in Mather are seeing the Crimson's full frontal page? Embarassed in Mather...
