The pull test in healthy subjects: Quantitative, posturographic and electromyographic analysis
Objective: To study the destabilizing force needed to reach the limit of stability (LoS), the displacements of the center of pressure (CoP) and the postural…Exploring the brainstem functions in cervical dystonia
Objective: To explore the exteroceptive brainstem reflexes in patients with cervical dystonia. Background: Dysfunction of the inhibitory components along the motor system has been reported…Emotional modulation of the startle reflex in essential tremor: Evidence of altered cerebellar input into limbic circuitry?
Objective: To examine whether Essential Tremor (ET) is associated with subtle changes in emotion processing, in parallel with those observed in the cognitive domain, using…Single unit activity of globus pallidus during voluntary movements in patients with cervical dystonia
Objective: To reveal the electrophysiological mechanism of voluntary movements with and without neck muscle exertion in patients with cervical dystonia. Background: Globus pallidus, as part…Globus pallidus interna oscillatory activity differentiates tics from voluntary movements and the Parkinsonian resting state
Objective: To describe local field potential (LFP) characteristics during tic acivity, voluntary activity, and the Parkinsonian resting state. Background: Deep brain stimulation is an emerging…Movement execution but not preparation modulates somatosensory temporal discrimination thresholds in healthy subjects
Objective: The aim of the study was to investigate in healthy subjects whether somatosensory temporal discrimination threshold (STDT) is influenced by movement execution and preparation.…Stage dependent alteration of cortical excitability in patients with hepatic encephalopathy
Objective: To evaluate cortical excitability in patients with hepatic encephalopathy (HE) using transcranial magnetic stimulation (TMS). Background: HE is a neuropsychiatric disorder manifesting with movement…The regulation of ASIC1a on dopamine release and its implication in the pathogenesis of Parkinson’s disease
Objective: To study the distribution of acid-sensing ion channel 1a (ASIC1a) in dopaminergic neurons and its role in regulating dopamine release, and to explore its…Single unit activity of medial thalamus during goal-directed motor and cognitive behavior in patients with cervical dystonia
Objective: To 1) study neuronal activity of medial thalamic nuclei (MD, CM-Pf) and its role in cognitive and motor human activity and 2) evaluate neuronal…Inferring the causal interplay of motor related brain areas in the aging brain: A dynamic causal modeling (DCM) approach
Objective: To investigate the causal interplay of brain areas during the performance of a complex bimanual motor task in young and elderly subjects. Background: Coordination…
