How mirror neurons allow us to learn and socialize by going through the motions in the head

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience. It turns out that humans, primates, some birds, and possibly other higher animals have mirror neurons that fire in the same pattern whether per...
