Question: Do we still not know everything our brain does?

Ian van der Linde answered on 21 Jun 2011:

We know a small amount about how the brain processes information – and for me in particular, visual information. What we do know quite a bit about is which areas of the brain are used in specific tasks – like which areas are used for speech, motor control, hearing, smell,etc. We just know relatively little about exactly how they do their job and exactly how they are all interconnected.
