Hitting a Baseball Needs the Brain

This may seem strange, but it is true: almost everything you do is controlled by your brain, even things you might not “think” about. For example, if you sit down to do some particularly difficult math homework, the parts of your brain that allow you to manipulate numbers and solve problems, like the prefrontal cortex, will be working in overdrive. But even for relatively “simple” things, like looking around the room and recognizing a table or a chair, is controlled by the activity of the brain, even if it is not something you have to think hard to do (Figure 1).
