Specific brain circuitry, responsible for causing overeating, has been discovered by researchers at the University of North Carolina's School of Medicine.The findings, published in the journal Science, offer a new look into the neuroscience of obesity, also offering hope for the development of treatments for anorexia and bulimia. The research team focused on a single cell in the brain that controls emotion. By stimulating the cell in mice brains, they found that the animals would reduce their food intake by half."The study underscores that obesity and other eating disorders have a neurological basis. With further study, we could figure out how to regulate the activity of cells in a specific region of the brain and develop treatments," said Garret Stuber, lead author of the study.He added that the further study of such brain cells could lead to the development of drugs to treat specific populations of patients who suffer from eating disorders.
