Inset shows higher resolution confocal
images of photoreceptor cell nuclear layers (DAPI blue) and rhodopsin expression (red) in the dystrophic control (left inset) and dystrophic with iPS - RPE transplant (right inset) RCS rat.

It took nearly eight decades for scientists to investigate his claim and prove him right: The eye really does contain a third type
of photoreceptor cells that sense light intensity without detecting
images.
At the top
of the
image are the retina's
photoreceptor cells (in gray)-- the familiar rods and cones — that capture photons
of light and translates them into electrical currents.
Confocal
images of P150 dystrophic retina transplanted with hNPCctx — GDNF and double stained with antibodies against human nuclear antigen (red) and either (A) recoverin, a
photoreceptor and cone bipolar
cell marker (green), or (B) protein kinase Cα (PKCα), a bipolar
cell marker (green).
The Argus II's 60 electrodes are trying to do the job
of the eye's roughly 125 million
photoreceptor cells, so it's not surprising that they produce extremely crude
images.
