Brain Gain
The underground world of “neuroenhancing” drugs.
by Margaret Talbot
Alex recalled one week during his junior year when he had four term papers due. Minutes after waking on Monday morning, around seven-thirty, he swallowed some “immediate release” Adderall. The drug, along with a steady stream of caffeine, helped him to concentrate during classes and meetings, but he noticed some odd effects; at a morning tutorial, he explained to me in an e-mail, “I alternated between speaking too quickly and thoroughly on some subjects and feeling awkwardly quiet during other points of the discussion.” Lunch was a blur: “It’s always hard to eat much when on Adderall.” That afternoon, he went to the library, where he spent “too much time researching a paper rather than actually writing it—a problem, I can assure you, that is common to all intellectually curious students on stimulants.” At eight, he attended a two-hour meeting “with a group focussed on student mental-health issues.” Alex then “took an extended-release Adderall” and worked productively on the paper all night. At eight the next morning, he attended a meeting of his organization; he felt like “a zombie,” but “was there to insure that the semester’s work didn’t go to waste.” After that, Alex explained, “I went back to my room to take advantage of my tired body.” He fell asleep until noon, waking “in time to polish my first paper and hand it in.”
AND.....
Both Chatterjee and Farah have wondered whether drugs that heighten users’ focus might dampen their creativity. After all, some of our best ideas come to us not when we sit down at a desk but, rather, when we’re in the shower or walking the dog—letting our minds roam. Jimi Hendrix reported that the inspiration for “Purple Haze” came to him in a dream; the chemist Friedrich August Kekule claimed that he discovered the ring structure of benzene during a reverie in which he saw the image of a snake biting its tail. Farah told me, “Cognitive psychologists have found that there is a trade-off between attentional focus and creativity. And there is some evidence that suggests that individuals who are better able to focus on one thing and filter out distractions tend to be less creative.”
