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.

R7 photoreceptors require the endosomal protein Lost and Found to form stable connections only when this protein is also present in neurons that are synaptic partners of R7.

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.

The ribbon synapses of zebrafish UV-cone photoreceptors preferentially transmit transient or sustained components in light-stimuli depending on their location in the eye.

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.
