Photoreceptor processing speed and input resistance changes during light adaptation correlate with spectral class in the bumblebee, Bombus impatiens. [PDF]

open access: yesPLoS ONE, 2011
Colour vision depends on comparison of signals from photoreceptors with different spectral sensitivities. However, response properties of photoreceptor cells may differ in ways other than spectral tuning. In insects, for example, broadband photoreceptors,

Impact of photoreceptor density in a 3D simulation of panretinal laser photocoagulation

open access: yesBMC Ophthalmology, 2021
Background During panretinal photocoagulation (PRP), the outer retina, especially the photoreceptors, are destroyed. During such procedures, the impact of the retinal photocoagulation, which is performed in the same photocoagulated area, may change if it

Data on mitochondrial ultrastructure of photoreceptors in pig, rabbit, and mouse retinas

open access: yesData in Brief, 2020
Photoreceptors are one of the most energy-consuming cell types within the human body. To meet their high energy demand, photoreceptors possess a mitochondrial cluster in the inner segment of the cell.

Disrupting the ciliary gradient of active Arl3 affects rod photoreceptor nuclear migration

open access: yeseLife, 2023
The small GTPase Arl3 is important for the enrichment of lipidated proteins to primary cilia, including the outer segment of photoreceptors. Human mutations in the small GTPase Arl3 cause both autosomal recessive and dominant inherited retinal ...

Bat eyes have ultraviolet-sensitive cone photoreceptors [PDF]

open access: yes, 2009
Mammalian retinae have rod photoreceptors for night vision and cone photoreceptors for daylight and colour vision. For colour discrimination, most mammals possess two cone populations with two visual pigments (opsins) that have absorption maxima at short

Derivation of Traceable and Transplantable Photoreceptors from Mouse Embryonic Stem Cells

open access: yesStem Cell Reports, 2014
Retinal degenerative diseases resulting in the loss of photoreceptors are one of the major causes of blindness. Photoreceptor replacement therapy is a promising treatment because the transplantation of retina-derived photoreceptors can be applied now to ...
