How does deep brain stimulation implant work?

Pacemaker for Brain: In many ways a deep brain stimulator access a pacemaker for the brain. It sends electrical impulses to specific parts of the brain. In select brain regions has provided remarkable benefits for otherwise treatment-resistant movement and affective disorders such as chronic pain, Parkinson's disease, tremor and depression.

HOW DBS WORKS!: DBS works by implanting an electrode in a nucleus of brain.The target varies depending on what is being treated.The electrode has contacts on it that can be programmed by changing the voltage, pulse width and frequency which can be programed 2 weeks to a month after surgery by a neurologist.The electrical signal either inhibits or stimulates the nucleus changing the firing pattern of Neurons.
