When light strikes cis-retinal in the disks in the rods and cones , cis-retinal changes to all-trans-retinal which then triggers changes in the opsins. Photoreceptor axons obliquely orientated fibres; not present in mid-peripheral or peripheral retina. The mammalian photoreceptor amplification process uses large quantities energy for vision in photopic conditions requiring less under scotopic conditions and, thus, requires the large supply nutrients supplied by the blood vessels in the choroid, which lies beyond the RPE. Beyond this simple difference, ganglion cells are also differentiated by chromatic sensitivity and the type of spatial summation. Zeichenbeschränkung: In some lower vertebrates e.

Although their photoreceptors contain a protein, retinochrome, that recycles retinal and replicates one of the functions of the vertebrate RPE, one could argue that cephalopod photoreceptors are not maintained as well as in vertebrates and that, as a result, the useful lifetime of photoreceptors in invertebrates is much shorter than in vertebrates.
