Eksempler på octopus

• 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.

• The "octopus grip" became both a description of economic reality and also a cultural ideal.

• Because we didn't know, he answered the question himself: like an octopus.

• A microtubule-based cytoskeleton may direct the other light 0 dark changes, including photopigment movements and pigment granule migration, which occur in the octopus retina.

• Toward this goal, we have localized actin-binding proteins in octopus rhabdoms and have shown that light and dark affect the distribution of these proteins.

• Retinoid cycling proteins redistribute in light-0 dark-adapted octopus retinas.

• We suggest that light may regulate the distribution of microtubule cytoskeletal proteins in the octopus retina and that position, dorsal versus ventral, also influences the distribution of motor proteins.

• We believe that signaling cascades control cytoskeletal organization in the octopus photoreceptor and direct the light 0dark changes in rhabdom structure and organelle movement we have observed.
