A Chain is Only as Strong as its Weakest Link: the Microelectrode
The targets for Deep Brain Stimulation (DBS) for movement disorders are not the subthalamic nucleus (STN), globus pallidus interna (GPi) or the ventral intermediate nucleus of the thalamus (Vim). It is the sensori-motor region of the STN. It is the motor homunculus appropriate to the patient’s symptomology in the GPi and Vim. To date, the […]
Risk Involved in Advancing Microelectrodes with Tips Withdrawn
We recently learned that some intraoperative neurophysiologists and neurosurgeons utilize the large indifferent or reference electrical contact for macrostimulation during targeting of the Deep Brain Stimulation (DBS) lead. Such macrostimulation may be useful to infer the regional anatomy and physiology of the electrode location and to, perhaps, anticipate post-operative clinical response. Those interested in a fuller […]
