I've been kind of obsessed with neuroscience lately. The study of our brains has made some amazing leaps in the past decade or so, particularly when it comes to how we understand our children's minds. Behind many of those leaps have been advances in brain scans. Scientists have been able to use non-invasive magnetic resonance imaging to study adult brains for some time. But young kids were just too squirmy for the most detailed types of scans. Now, though, scientists are starting to figure out ways to see what's going on in developing brains, regardless of the squirms.
