The authors suggest that this 'eye' did not exhibit image-forming capabilities, and that its function was instead non-visual (possibly circadian). Comparison of photoreceptor ultrastructure across ...

The human eye is reasonably fast ... which improve their owners’ vision by focusing light onto underlying photoreceptors. But unlike opsins, with their single dynasty, crystallins are unified ...

subtle eye movements, and the unique arrangement of photoreceptor cells in the human eye. Published in the journal eLife, the research provides new insights into how our visual system achieves ...

And we use essentially the eye, at least the human eye, like a camera. Instead of a film, you have a retina in the back, with photoreceptor cells, and this makes the eye a very fascinating organ.

In the case of the common and well–studied blue tit bird, the male and female appear visually identical to the human eye.

The researchers plan to refine the protocol and test against cells in photoreceptor degeneration that are more closely related to the human eye. If practical, they hope to start clinical trials.

aipl1b mRNA is expressed exclusively in photoreceptors, especially all types of cones at the adult stage. B: Microscopic images of wild-type and gosh mutant retinas at 3 months-post-fertilization.
