If you’re interested in losing weight and aren’t afraid of having your brain controlled by a laser beam through your eyeballs, then science has the perfect solution for you. In a recent study involving mice, scientists think they have discovered the part of the brain that allows for overeating – and how to turn it off.
The neuroscientists modified the mice so that the specific neurons they were targeting would respond to light differently. In one group of mice, light would activate that specific part of the brain and, in the other group of mice, light would disable it. By shining a laser through the eyeballs of the mice into their brains, the scientists could then effectively activate or disable that part of the brain.
