Deep brain stimulation is not only used in Parkinson's disease but also helps to balance uncontrollable emotions and sensations in depression. There are basically three key regions in the brain to be considered for electrical stimulation. Above all the nucleus accumbens is thought to be related to the development of depression and it is hence the target area for patients with severe depression. During a stereotactic surgery the neurosurgeons implant minute electrodes into the respective brain region with millimeter precision. With short and high frequency electrical impulses neuronal circuits are modulated and pathological nerve signals corrected. The stimulation parameters (amplitude, frequency, impulse width) are adjusted to obtain the best effects. The actual "brain pacemaker" on the chest muscle is connected to the brain electrodes through wires under the skin.
