Eye, Brain and Vision

This work examines the mechanisms by which we perceive colour, depth and movement, and the function of the fibres connecting the two halves of the brain. The author describes how the visual circuits develop before birth and discusses the unexpected consequences of visual deprivation early in life. He describes current knowledge concerning the higher visual areas of the brain known as 18, V4 and MT. The tasks scientists face in deciphering the remaining mysteries of vision and the workings of the human brain are also explored.
