Overview:

This episode takes viewers on a fascinating tour of our visual world, from the moment light enters our eyes, to the way this information is transformed into electrical impulses and decoded by our brain - the domain of "visual perception". The act of "seeing" takes an immense amount of brainpower, more than 65% of the brain's neural pathways.
