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.
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.
Retinoid cycling proteins redistribute in light-0 dark-adapted octopus retinas.
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.
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.
Because we didn't know, he answered the question himself: like an octopus.
The "octopus grip" became both a description of economic reality and also a cultural ideal.
No changes in the octopus retina immediately following an intense light flash.
