Brain implants have been around for years with one of the first being the Cochlear Implant which improved hearing ability. In recent years, more and more medical devices have been toggling with the capabilities of brain implants to cure diseases, medical conditions and birth defects.
The Deep Brain Stimulator is a brain implant that has been rolled out within the last few years to cure diseases such as Parkinsons. It uses two electrodes connected to the brain that interrupt the synapse between nerves. This means that the implant is able to alter the information the brain receives in order to change the motion of the body. This is the first wave of invasive brain implants with the capability to control movement and interrupt normal bodily function.
