Functional subtypes of rodent melanopsin ganglion cells switch roles between night and day illumination.

The paper identifies 8 functional subtypes of rodent ipRGCs and shows they have distinct photosensitivity and response timing, with varying performance under different light conditions.

Restoration of high-sensitivity patterned vision in motion with an engineered light-gated G protein-coupled receptor

This paper demonstrates a chemical-optogenetic approach that restores high-sensitivity motion vision in an IRD mouse model using a multi-branched photoswitch.

A subtype of melanopsin ganglion cells encodes ground luminance

The paper identifies a subtype of ipRGCs projecting to the SON and shows they encode ground luminance through a non-overlapping tiled mosaic in the dorsal retina.
