With millions of people overweight, and dieting, researchers believe they can control memories of food that would make humans forget they want food.
Kelsey Seybold's Dr. Christine Le said they are able to change the neurons in mice brains so when they see food, they don't eat it.
"In humans, I think it may not be so easy. I don't think that there's a quick brain zap that we can do to humans, so that when we see the cake we don't eat it," said Le.
Scientists claim hD2R neurons make eating less rewarding.
Researchers think this could help humans to undo the way they've been seeing food, and form a new perception.
