Craving a certain snack, getting it from the fridge or at the store, then the joy of eating it. It’s a familiar ritual for most of us. Scientist say we are performing appetitive and consummatory behavior, and the part of our brain that regulates these behaviors is the lateral hypothalamus (LH). You can imagine that this is an important element in the investigation of, for example, addiction and eating disorders. The problem is that the LH seems to be a mosaic of different neurons with different functions, making it difficult to specifically target them.
