Voorbeelden van rod

• For nocturnal or deep-sea animals, the sensitivity afforded by achromatic rod vision may outweigh the benefits of cone-based color constancy.

• Thus, we can conclude with confidence that rod cells do not contain a circadian oscillator.

• Synaptic transmission mediated by internal calcium stores in rod photoreceptors.

• The regulatory elements are able to direct expression to a subpopulation of cones while excluding expression in rods and non-photoreceptor retinal cells.

• Increase in retinal area, density of rod nuclei, and densities of rod inner and outer segments were also studied in these and additional species.

• Furthermore, two different patterns of distribution of rod precursors were distinguished.

• Topography of cones and rods in the tree shrew retina.

• The high density of rods (104,100 cells/mm2) with elongated outer segments (up to 30.5 6 2.9 m in length) indicates a light-sensitive retina.
