Deep Brain Stimulation Program

DBS treats the functional characteristics of various movement and psychiatric disorders, including Parkinson's disease, essential tremor, dystonia, and obsessive-compulsive disorder.

The success of DBS therapy depends upon accurate placement of the DBS lead, which allows maximal treatment efficacy and battery life, with minimal stimulation-induced side effects. Intraoperative microelectrode recording and stimulation-mapping allows the identification of deep brain structures that are not fully identified in CT or MRI image sequences. Our neurophysiologists provide expert technical interpretation of this information to help guide the surgeon to the optimal location to implant the permanent DBS lead. All of this can be accomplished without adding significant time to the surgery. Just as DBS improves the patients quality of life, our monitoring improves the quality of DBS therapy.

Microelectrode mapping involves the insertion of temporary microrecording electrodes into the brain with the goal of identifying the unique neurophysiological signature of anatomical structures targeted for DBS. To ensure the degree of accuracy needed to achieve optimal results, we only use PhD neurophysiologists with extensive experience in microelectrode mapping, and strong research credentials. Our neurophysiologists receive hands-on training from the Directors of DBS service at our main DBS facility located at Vanderbilt University, in Nashville Tennessee. Working alongside Vanderbilt's Director of Functional Neurosurgery, our team has developed a state-of-the-art clinical and research facility whose goal is continuous improvement in the efficiency and accuracy of DBS neurophysiology.

We offer a highly customized service that is specific to the requirements of both the surgeon and their hospital:


  • Our mapping protocols are tailored to meet the needs of the individual neurosurgeon, and we can provide single or multiple microelectrode recording (with or without somatotopic mapping) and stimulation mapping, to maximize treatment efficacy and minimize stimulation induced side effects.
  • We can provide full or partial equipment solutions for hospitals lacking the specialized capital equipment required for DBS neurophysiology, or can work with in house neurophysiology systems from a variety of manufactures (FHC, Medtronic, Alpha Omega).
  • Upon request, our staff can provide technical consultation for surgical planning, stereotactic systems (CRW, Leksell, Starfix and Nexframe) neurophysiology equipment (Guideline 4000, LP+, Leadpoint, Microguide, and NeuroNav), and didactic support for the theoretical and scientific aspects of DBS therapy.
  • Sentient has provided Neurosurgeons with neurophysiological mapping during surgeries for movement disorders since 1999. Our focused approach has allowed Sentient to become the largest provider of DBS neurophysiology in the country, and we currently provide our DBS service at more than 40 hospitals. Our commitment to DBS ensures that you and your patient will receive the most experienced monitoring available, resulting in improved patient outcomes and reduced OR time.
