Researchers identified a brain circuit in mice that drives them to seek food even when not hungry, focusing on a specific group of cells in the brainstem's periaqueductal gray (PAG) area. This discovery highlights how stimulating these cells causes mice to prefer high-calorie foods and engage in food-seeking behaviors, regardless of hunger.
