In this study, we localized cytoskeletal and signaling proteins in octopus photoreceptors to determine their concurrence between the lighting conditions.
Presently, we have no understanding about the arrangement of microtubules or the distribution of associated motor proteins in the octopus retina.
Octopus photoreceptors are comprised of an inner segment, proximal region, and an outer segment.
Cephalopods (octopus, squids, and cuttlefish), despite a very advanced evolution of their visual system, were not able to evolve a large brain.
In these diagrams, the spatial organism looked pretty much like the digestive system of an octopus.
The visual acuity of octopuses for grating of different orientations.
Microtubules in octopus photoreceptors are probably involved in transpor t of organelles, including pigment granules, during dark and light adaptation.
No changes in the octopus retina immediately following an intense light flash.
