Despite evidence of retinal stretching with eye growth, cone photoreceptor sampling density in the foveal center of humans actually increases with eye length.

A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.

The recently characterized opsin group of xenopsins is likely a major player in animal eye evolution and may have been present in an ancient, highly plastic eye photoreceptor cell type.

In a zooplankton larva, ciliary and rhabdomeric photoreceptor cells work antagonistically to form a spectral depth gauge.

Birds that see ultraviolet light tune the sensitivity of their short-wavelength photoreceptors with colored filters to maximize the number of colors they can see.

The eye produces a protein that inhibits the growth of blood vessels in the deep retina, which includes the photoreceptor layer, and disruption of this process can lead to blindness.

A retinal gene regulatory network prevents the formation of alternative cell fates from non-stochastic retinal progenitor cells.

Heterogeneity in perceptual sensitivity of human cone-mediated vision across wavelength originates in the cone photoreceptors, where S cones exhibit distinct functional properties in comparison to L and M cones.

Correlating changes in structure and gene expression in cone photoreceptors of mice daily, between birth and eye opening, created a resource that supports research in photoreceptor function, development, transplantation and repair.

Ca2+ influx through Cav1.4 channels is required for the structural, but not the molecular organization of the rod photoreceptor synapse.
