An afoveate area centralis in the chick retina

J Comp Neurol. 1982 Sep 10;210(2):198-203. doi: 10.1002/cne.902100210.

Abstract

A specialization has been found in the nasal retina of late embryonic and newly hatched chicks of the domestic fowl. In whole mounts of the retina, there is a central node about 2 mm from the dorsal end of the optic disc and a set of structures radiating out from this node. This complex has been named the aster. Sections of the retina show that the structures which form the aster lie in the inner nuclear layer. The specialization has been classed as an afoveate area centralis.
