Bright light exposure suppresses feeding and weight gain via a visual circuit linked to the lateral hypothalamus

Nature Neuroscience, Published online: 12 December 2025; doi:10.1038/s41593-025-02156-1

Bright light reduces feeding and weight gain in mice by activating a specific retina-to-brain pathway that signals through the visual thalamus to inhibit appetite-regulating neurons in the hypothalamus.
