So far, specialist doctors have performed experimental surgery to stimulate the brain with electricity to relieve mental disturbances.

They start by making 2 small holes in the skull. Then they insert a wire into the brain through each hole. At the end of the cable is an electrode.

The battery is implanted in the patient’s chest, which is connected to the electrodes with a wire.

In this way, a small pulse of electricity can be sent to the brain which can change its stimulation in various parts of it and change its function nervously.

It is estimated that 280 million people worldwide suffer from advanced depression.
