A burgeoning research area in psychology is the idea of embodied cognition — that is, not only does your brain tell your body what to do, but it works the other way around, too. In other words, the position of your body can influence your thoughts. Your yoga teacher might call it the mind-body connection; a pair of U.K. researchers, on the other hand, recently described it in the journal Frontiers as "the surprisingly radical hypothesis that the brain is not the sole cognitive resource we have available to us to solve problems."
Here's a roundup of a few recent findings. (Oh, and a hat tip to the wonderful site PsyBlog for unearthing some of these first!)
