When humans look at the world around them, more than 100 million receptors in the retina are bombarded with photons of light.  The receptors translate the light energy into electrical signals which are then transmitted to the brain.  But how does the brain make sense of these signals and how does it process the staggering influx of information to a coherent image rich in form, colour, depth and movement?  Hubel, a researcher in the optics and vision field for over thirty years, explains.
