Deep brain stimulation (DBS) has been an alternative therapy for treating various neuro-degenerative diseases, such as Parkinson's disease. Usually the electrode shall be inserted at a specific site (i.e. subthalmic nucleus or STN for the case of Parkinson's disease), which is often surrounded by many delicate and vital structures to the healthy function of our brain. The accuracy of the electrode placement is crucial to the surgical outcome, and the understanding of the circuitry of the human brain. However, there is always a question regarding whether the stimulation electrode has been placed at the desired site inside the brain. Some believe that in some cases migrated or misplaced electrode can still result in positive surgical outcome, and this may raise the question of whether the conventional stimulation sites are the unique solution to the problem.
I ran across an interesting demonstration of the DBS procedure made by Dr. Jeremie Dequidt from INRIA (http://dequidt.plil.net/publications.php). The accompanied article will soon appear in the proceeding of MICCAI 2011.

Although the simulation may disclose some possible scenario during the DBS procedure, validation of the accuracy of the model should be further verified. However, the implementation of the validation can be highly complicated.
