...says Dr. Seymour Diamond, director of the Diamond Headache Clinic in Chicago. Intriguingly, the pain-fighting effect of antidepressants takes just three to 10 days to kick in, less than half the time needed to alleviate depression. This suggests that depression and migraine are triggered by different, though related, neural pathways...
This means that scientists can, in effect, switch off a person's grasp of numbers. It's fascinating, both because it reduces a serious learning disability to the mere flick of a neural switch and because, by doing so, it holds out a tantalizing possibility that one day a cure may be as simple as flicking that switch in reverse. Cohen Kadosh hopes the result will allow scientists to develop a diagnostic tool for dyscalculia based on neuroimaging. Identifying children with developmental dyscalculia would let parents intervene earlier to teach important math concepts, just as they can intervene today...
...dreaming and postulated new and intriguing ones, with experiments underway in various parts of the world aimed at establishing the function of our nightly hallucinations. If recent work suggests anything, it's that there is such a function, or more than one, and that dreams aren't just neural waste. They may improve the quality of our sleep. They may prepare us for danger. They may embed memories. There are more theories than answers. But after years in the doldrums, dream research is moving forward again...
...critics, who protested that many dreams aren't merely cognitive fragments nor a succession of chaotic images, but so story-like, sequential and dramatic that the thinking brain must surely have played a more substantial role in their production than the last-minute editing of a pile of neural bloopers. And there's the matter of lucid dreaming, in which people become aware in the course of a dream that they are, in fact, dreaming, and are able to control the course of events-a phenomenon that strengthens the case for higher-brain involvement in dream construction. The lucid dreamer...
...young children to care for. Hofstadter was overwhelmed by grief, and much of I Am a Strange Loop flows from his sense that Carol lives on in him--that the strange loop of her mind persists in his, a faint but real copy of her software running on his neural hardware, her tune played on his instrument. "It was that sense that the same thing was being felt inside her and inside me--that it wasn't two different feelings, it was the same feeling," Hofstadter says. "If you believe that what makes for consciousness is some kind of abstract...
