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.

• It may arise from melanopsin-generated input and 0or melanopsin-derived signals modified by rods and 0or cones.

• Characterization of the rod photoresponse isolated from the dark-adapted primate retina.

• This feedback has been shown to occur primarily at the axon terminals of rat rod bipolar cells.

• The rate of increase of ellipsoid volume, and therefore mitochondrial volume, with increased eccentricity, was much more dramatic in cones than in rods.

• In summary, we have quantified the difference between rods and cones in their mitochondrial content.

• There is similar agreement for comparisons of spectra based on rod signals for dog and ferret.

• A visual pigment expressed in both rod and cone photoreceptors.
