French neuroscientists have ended a long controversy, confirming a specific area of the human brain plays a causal role in our ability to recognize words. Humans have an uncanny ability to skim through text, instantly recognizing words by their shape — even though writing developed only about 6000 years ago, long after humans evolved. Thus, scientists have hotly debated whether an area of the cortex called the Visual Word Form Area, or VWFA, is a specific and necessary area for recognizing words.
