The advantages of dyslexia

With reading difficulties can come other cognitive strengths.  “There are three types of mathematicians, those who can count and those who can’t.”  Bad joke? You bet. But what makes this amusing is that the joke is triggered by our perception of a paradox, a breakdown in mathematical logic that activates regions of the brain located in the right prefrontal cortex. These regions are sensitive to the perception of causality and alert us to situations that are suspect or fishy — possible sources of danger where a situation just doesn’t seem to add up.
