WebSep 23, 2024 · Since its discovery, six subtypes of ipRGC have been described, each contributing to various image-forming and non-image-forming functions such as circadian photoentrainment, the pupillary light reflex, the photic control of mood and sleep, and visual contrast sensitivity. WebFeb 20, 2024 · Patterson et al. identify a new amacrine cell type in the primate retina with “blue” S-cone circuit input and targeted output to intrinsically photosensitive retinal ganglion cells (ipRGCs). This circuit may contribute to the effects of short-wavelength light on ipRGC downstream non-image-forming visual functions such as sleep, mood, and learning.
