Abstract
Essence
Bright light reduced feeding and weight gain in mice through a retina-vLGN-LHA visual circuit.
Evidence
Mouse neural-circuit experiments mapped SMI-32-expressing ON-type retinal ganglion cells to vLGN GABAergic neurons and LHA GABAergic neurons, with pathway activation suppressing food intake and weight gain.
Caveat
The findings are limited to mice and circuit-level manipulations, so they do not show that bright light therapy produces comparable weight effects in humans.
