Molecular glucose imaging reveals functional brain reconfiguration by subthalamic deep brain stimulation in Parkinsonian rats

Translational Neurodegeneration
Background In order to elucidate the neuromodulatory mechanisms underlying therapeutic subthalamic deep brain stimulation (DBS), we here reverse-translate a methodological pipeline that integrates neurostimulation effect parameterization and molecular ...

Subcortical correlates of consciousness with human single neuron recordings

eLife
Subcortical brain structures such as the subthalamic nucleus or the thalamus are involved in regulating motor and cognitive behavior. However, their contribution to perceptual consciousness remains unclear, due to the inherent difficulties of recording ...

Acute hemiballismus in the absence of subthalamic nucleus lesion

MGM Journal of Medical Sciences, 2020
A 68-year-old male, known hypertensive on irregular medication presented with sudden onset of involuntary movements of the left upper limb, in the form of severely violent, arrhythmic, and flinging large amplitude movements for 2 days, suggestive of ...

Effects of aging on nitrergic neurons in human striatum and subthalamic nucleus

Arquivos de Neuro-Psiquiatria, 2015
Nitric oxide (NO) is a major neurotransmitter associated with motor control in basal ganglia. Movement disorders, as essential tremor and Parkinson’s disease, are more prevalent on aged individuals.

Hypotensive Episodes Precede Cognitive Fluctuations in Parkinson's Disease Dementia

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Cognitive fluctuations (CFs) are a disabling feature in Parkinson's disease dementia (PDD) and contribute to caregiver burden. The relationship between CFs and neurogenic orthostatic hypotension (nOH), a common autonomic complication in PDD, has not been adequately examined.

Quantifying local field potential dynamics with amplitude and frequency stability between ON and OFF medication and stimulation in Parkinson's disease

Neurobiology of Disease
Neural oscillations are critical to understanding the synchronisation of neural activities and their relevance to neurological disorders. For instance, the amplitude of beta oscillations in the subthalamic nucleus has gained extensive attention, as it ...

Homogenous Cell Transplantation Trials in Parkinson's Disease: A Systematic Review and Meta‐Analysis

Movement Disorders Clinical Practice, EarlyView.
Abstract Background The transplantation of homogenous cells has emerged as an investigational strategy for Parkinson's disease (PD), offering an alternative to symptomatic treatment. Objective We performed a systematic review and meta‐analysis to assess its clinical efficacy and safety.
