Researchers have found that over-eating could be controlled through a brain circuit linked to feasting. The state of impulsivity has been linked to eating disorders that can lead to threats like that of obesity, which later can have several psychiatric disorders including drug addiction. A study on this can possibly make scientists develop certain therapeutics to address the issue of over-eating. A team that includes a faculty member at the University of Georgia has now identified a specific circuit in the brain that alters food impulsivity. The team's findings were published recently in the journal Nature Communications. Emily Noble, an assistant professor in the UGA College of Family and Consumer Sciences who served as lead author on the paper said: "There is underlying physiology in your brain that is regulating your capacity to say no to. In experimental models, you can activate that circuitry and get a specific behavioural response." The study noticed that a group of brain cells that produce a type of transmitter in the hypothalamus called melanin-concentrating hormone (MCH) is what to be focused on.
