Targeting the subthalamic nucleus.
The small size and surrounding neuronal structures and fibre tracts make the STN a difficult stereotactic target. In this article we present the technique used by us to target the STN. Our combined experience from two centres comprises 18 lesions and 27 stimulator implants in the STN. Our criteria for patient selection and the use of MRI, frame-on CT and volumetric image fusion are presented. T...
متن کاملSubthalamic nucleus stimulation modulates thalamic neuronal activity.
Deep brain stimulation (DBS) in the subthalamic nucleus (STN) is an effective tool for the treatment of advanced Parkinson's disease. The mechanism by which STN DBS elicits its beneficial effect, however, remains unclear. We previously reported STN stimulation increased the rate and produced a more regular and periodic pattern of neuronal activity in the internal segment of the globus pallidus ...
متن کاملThe role of the subthalamic nucleus in response inhibition: Evidence from local field potential recordings in the human subthalamic nucleus
Response inhibition as measured during a stop-signal task refers to the ability to halt an action that has already been set in motion. Cortical and sub-cortical structures, such as the subthalamic nucleus (STN), that are active during attempts to inhibit action are thought to contribute to a 'stop-process' that must gain dominance over a 'go-process' if inhibition is to be successful. We record...
متن کاملSubthalamic nucleus and globus pallidus internus stimulation for the treatment of Parkinson’s disease: A systematic review
Objective Deep brain stimulation (DBS) for treatment of advanced Parkinson's disease (PD) has two anatomical targets: the subthalamic nucleus (STN) and the globus pallidus internus (GPI). The clinical effectiveness of these two stimulation targets was compared in the present study. Methods A systematic review and meta-analysis was performed to evaluated the postoperative changes in the United P...
متن کاملRoles of the subthalamic nucleus and subthalamic HCN channels in absence seizures.
Absence seizures consist of a brief and sudden impairment of consciousness. They are characterized by bilaterally synchronized spike and wave discharges (SWDs), which reflect abnormal oscillations in the thalamocortical loops. Recent studies have suggested that the basal ganglia are involved in generation of the SWDs, but their roles are poorly understood at the molecular and cellular levels. H...
