Subthalamic 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 کاملSubthalamic Nucleus Electrical Stimulation Modulates Calcium Activity of Nigral Astrocytes
BACKGROUND The substantia nigra pars reticulata (SNr) is a major output nucleus of the basal ganglia, delivering inhibitory efferents to the relay nuclei of the thalamus. Pathological hyperactivity of SNr neurons is known to be responsible for some motor disorders e.g. in Parkinson's disease. One way to restore this pathological activity is to electrically stimulate one of the SNr input, the ex...
متن کاملSubthalamic nucleus stimulation reverses spinal motoneuron activity in parkinsonian patients.
Although a cardinal symptom of Parkinsonian disease, up to now, rigidity has been investigated much less than spasticity in hemiplegic patients. Many pathophysiological mechanisms may at least theoretically contribute to Parkinsonian rigidity, from altered viscoelastic muscle properties to inability of parkinsonian patients to relax. However, as demonstrated many years ago, motoneuron responses...
متن کاملBrain networks modulated by subthalamic nucleus deep brain stimulation.
Deep brain stimulation of the subthalamic nucleus is an established treatment for the motor symptoms of Parkinson's disease. Given the frequent occurrence of stimulation-induced affective and cognitive adverse effects, a better understanding about the role of the subthalamic nucleus in non-motor functions is needed. The main goal of this study is to characterize anatomical circuits modulated by...
متن کاملSubthalamic nucleus stimulation influences expression and suppression of impulsive behaviour in Parkinson's disease.
Past studies show beneficial as well as detrimental effects of subthalamic nucleus deep-brain stimulation on impulsive behaviour. We address this paradox by investigating individuals with Parkinson's disease treated with subthalamic nucleus stimulation (n = 17) and healthy controls without Parkinson's disease (n = 17) on performance in a Simon task. In this reaction time task, conflict between ...
