Scientists discover new brain neurons that may help regulate hunger

Scientists have discovered a new type of neuron called BNC2, which quickly inhibits hunger-promoting neurons in the brain. This finding enhances our understanding of how appetite is regulated and could lead to new treatments for obesity and metabolic disorders. BNC2 neurons, located in the arcuate nucleus of the brain, respond rapidly to hunger signals. They act faster than previously known neurons that promote feelings of fullness, providing a more immediate counterbalance to hunger. This research suggests that targeting BNC2 neurons may help develop therapies for appetite regulation. The discovery also raises questions about similar neural circuits that may control other instinctive behaviors.
