A suprachiasmatic nucleus projecting retinal ganglion cell exhibits an unusually large dendritic field in the hamster

Neuroreport. 2006 Oct 2;17(14):1469-72. doi: 10.1097/01.wnr.0000234757.26610.e8.


The majority of retinal ganglion cells innervating the suprachiasmatic nucleus are intrinsically light sensitive, while the rest are conventional ganglion cells that collect inputs through conventional photoreceptors. Here we report a rarely encountered ganglion cell that had a dendritic field covering approximately 14.4% of retinal surface and its processes ramified in both the inner and the outer plexiform layers. This cell could have a potential role in detecting luminance changes over a large area of retinal surface.
