Researchers discover how opsin 3, a light-sensitive brain protein, regulates food consumption in mice

Scientists discovered years ago that the hypothalamus — which helps to manage body temperature, hunger, sex drive, sleep and more — includes neurons that express the protein opsin 3 (OPN3). Far less clear, however, was what this light-sensing protein does so deep inside the brain. A study published in PNAS suggests that OPN3 plays an important role in regulating food consumption.  “Our results uncover a mechanism by which the nonvisual opsin rec…
