Constant dendritic coverage by ganglion cells with growth of the goldfish's retina.

This study demonstrates that in the retina of the goldfish a type of ganglion cell, whose dendritic development has been well characterized [Hitchcock P.F. and Easter S. S. Jr (1986) J. Neurosci. 6, 1037-1050], is distributed across the retina in a nonrandom pattern, and the dendritic fields of this cell type overlap to completely cover, or "tile" the retina. Further, it is shown that the dendritic coverage of the retina by this cell type is established when the retina is small and is maintained as the retina grows.
