A clinical trial will aim to identify the pattern of brain activity that signals the start of a food binge

Six morbidly obese people have agreed to take part in a clinical trial of a brain chip that zaps them when they think about food.

The chip, known as a responsive neurostimulation system (RNS), was originally developed by medical technology company NeuroPace to treat people with epilepsy.

Once implanted in the brain, it records brain activity continuously, and delivers a mild electric shock whenever it detects a specific pattern of activity that signals the onset of a seizure.

This shock is designed to stop the seizure before it begins.

A recent research study published in the Proceedings of the National Academy of Sciences demonstrated that the same technique could be used to suppress binge-eating behaviour in mice. Read more
