Scripps Research Unveils Brain Neurons That Control First Bite and Drinking Behavior

Do you grab a fork and take a first bite of cake, or say no and walk away? Our motivation to eat is driven by a complex web of cells in the brain that use signals from within the body, as well as sensory information about the food in front of us, to determine our behaviors.
