Last week, a team from Medtronic of Minneapolis, Minnesota, reported on their design for a neurostimulator at the Engineering in Medicine and Biology Society meeting in Minneapolis. The devices use electrodes to deliver deep stimulation to specific parts of the brain.
Neurostimulators are already approved to treat conditions such as Parkinson's disease, essential tremor, and dystonia, as well as obsessive compulsive disorder. But existing devices deliver stimulation on a set schedule, not in response to abnormal brain activity. The Medtronic researchers think a device that reacts to brain signals could be more effective, plus the battery would last longer, an important consideration for implantable devices.

By adding a detection mechanism, designers dramatically improve the control function, and as a consequence the overall efficiency of the system.
