Introduction

The first episode of season four, the nerro science of neuro plasticity. If we take people who were born blind, or have been blind for some time, and we examine their brains using neuro maging, we see something quite interesting. For those of us who have intact sight, the largest sensory area of the brain is the visual system. The number of neurons dedicated to processing vision is larger than the total number of sensory neurons for the other four senses combined.
