Scientists have identified neurons in an evolutionarily ancient part of the brain that control when you stop eating a meal — at least in rodents.
The researchers discovered that cholecystokinin (CCK) neurons — which are found in the brain stem, one of the oldest parts of the brain — integrate various signals produced as we eat, causing us to feel full and not want to take another bite. The scientists described their findings in a new study published Wednesday (Feb. 5) in the journal Cell.
