A worker honey bee must feel hunger not only for herself, but for the whole hive. By examining cells within the honey bee brain that help regulate this hunger sense, scientists can learn more about how the brain tracks nutritional state, and how it controls behavior. This image shows an intact slice of a honey bee brain (bottom); a laser was used to dissect out nutrient-sensing brain cells (top), leaving the rest of the slice (middle) behind.
