This would be a whole lot easier—this quest for ways to improve our brain—if scientists understood the mechanisms of intelligence even half as well as they do the mechanisms of, say, muscular strength, says Newsweek. If we had the neuronal version of how lifting weights increases strength (chemical and electrical signals increase the number of filament bundles inside muscle cells), we’d be good to go. For starters, we could dismiss claims for the brain versions of eight-second abs—claims that if we use this brain-training website or practice that form of meditation or eat blueberries or chew gum or have lots of friends, we will be smarter and more creative, able to figure out whether to do a Roth conversion, remember who gave us that fruitcake (the better to retaliate next year), and actually understand the NFL’s wild-card tiebreaker system. But what neuroscientists don’t know about the mechanisms of cognition—about what is physically different between a dumb brain and a smart one and how to make the first more like the second—could fill volumes. Actually, it does……Read More
