Some Biochemical Aspects of the Development of Avian Optic Centres and the Effects of Deafferentation
The optic pathway of birds, connecting the retina to the tectum mesencephali, has often provided a suitable model for studying the pattern of connection between two developing nervous centres. Also for studying the mutual influences between two populations of neuroblasts, the complex optic pathway-optic centres lends itself as a good study model because its structure is rather well known and its anatomical position allows easy accessibility to experimental manipulations during embryonic life. In particular, since the chick optic pathway is completely crossed and provides the largest supply of fibres to the tectum, the removal of one retina deprives the contralateral tectum of most afferent fibres but leaves the ipsilateral one quite unaltered for control purpose.
