Nerve Amplifier Belt
this ancient device, created during the decades leading up to the Great Sith War, was used to monitor the brain activity of its wearer. These belts were originally created to retrain or alter the inherent "programming" of an individual being, and was known for its uncomfortable fit. The belt generated energy waves to help reinforce certain patterns of activity, thereby establishing a certain kind of behavior in the wearer. The belt could also be used to block any outside influence on an individual's brain.
