...organized sports. The human body is a sturdy one, but only up to a point, able to withstand collisions of about 15 m.p.h., which is about as fast as an average person can run. The skull is designed to be especially rugged - the permanent home and helmet for the brain - but even it can't take a much more serious hit. The problem is that over the centuries, we've developed all manner of ways to exceed a mere 15 m.p.h. creep. (Read a TIME cover story on the brain...
...most common collision-related head injuries is a concussion, which occurs when the head moves at high speed and stops suddenly as it strikes a hard object. The brain, which is snug but not completely stationary inside the head, may continue moving, colliding with the inside of the skull. This leads to swelling or bruising or - much worse - bleeding. A brain-bleed is immediately life-threatening, but swelling is less so and may not even be evident for a little while, which is what appears to have happened in Richardson's case...
...Once you do fall and hit, the brain can do much more than just bump the inside of the skull. "You can have stretching of cortical connections or stretching of blood vessels, and that can lead to bleeding," Shealy says. "You can also have linear or rotational acceleration [of the brain]. There's a lot that can go wrong in there...
...Either way, you're going to make a mess, and surprisingly fast. Volkow points out that even without increasing dopamine output, modafinil blocks the re-uptake of more than half the amount the brain naturally releases. "This completely negates the argument that modafinil has no dopaminergenic effect," she says. "It does have the drug signature required to produce addiction." The safe party drug, once again, is not nearly as safe as it seems...
...luminaries in the American conservative tradition. His father, Irving Kristol, chartered the school of thought known as “neoconservatism,” and he studied for his doctorate under Harvey C. Mansfield, Jr., ’53, conservativism’s elder statesman and principal brain trust. Despite these credentials, Mr. Kristol’s short run on the Times’s editorial page had yielded little more than uninspired boilerplate. With Mr. Douthat taking his stead, the Times will now feature a conservative whose intellectual vintage is much younger but who has already earned a reputation...
