On the Understanding of the Visual Pathways’ Dependence on the Visual Environment
- 100 Downloads
A great deal has been learnt in recent years concerning the postnatal development of the visual pathways, and the dependence of that development on visual experience. Important concepts have emerged, such as the critical period of maturation, the plasticity of stimulus specificities of individual cortical neurons, and the competition of the two eyes for synaptic space on cortical cells. The purpose of this chapter is not, however, to review this extensive literature, but to argue that, particularly in the cat, our understanding of the impact of visual experience on the development of the visual pathways has been both deepened and simplified by analysis of that impact in terms of the functional groupings of ganglion cells.
