Development of the visual system

The chapter starts with a brief outline of how eyes evolved from simple eyespots to complex camera-like eyes. An account of the development of the visual system starts with a description of methods used to study neural development. A description of the mechanisms that guide development of the eye and visual pathways is followed by an account of the development of the brain. Topics include axonal guidance, synaptogenesis, formation of cortical layers and connections, neural plasticity, and formation of ocular dominance columns in the visual cortex. An account is given of recently discovered epigenetic mechanisms in which stimulus-induced neural activity controls genes that express the proteins required in each location of the developing visual system.

Keywords: evolution of eyes; development of the brain; growth of the visual system; neural plasticity; epigenesis
