photoreception

Examples of photoreception in the following topics:

• Anatomy of the Eye

  • The retina, a thin layer of cells located on the inner surface of the back of the eye, consists of photoreceptive cells, which are responsible for the transduction of light into nervous impulses.
  • The retina contains photoreceptive cells.

• Convergent Evolution

  • Their last common ancestor had at most a very simple photoreceptive spot, but a range of processes led to the progressive refinement of this structure to the advanced camera eye.

• Modern Reptiles

  • They are also unusual in having a pronounced photoreceptive eye, dubbed the "third eye", whose current function is a subject of ongoing research, but is thought to be involved in setting circadian and seasonal cycles.
