Saccades in Parkinson’s disease: Hypometric, slow, or maladaptive?
Objective: Quantitatively study visually-guided saccades (VGS) in Parkinson’s disease (PD). Background: Visuomotor deficits such as hypometric VGS are present in PD despite the retained ability…Corticomuscular and Intermuscular Coherence as a Biomarker of Pallidal Deep Brain Stimulation Efficacy in Dystonia
Objective: To find a biomarker of GPi-DBS efficacy in dystonia. Background: GPi-DBS has been proven effective and safe in medically refractory dystonia. However, the heterogeneity…Dissociate effect of dopaminergic therapy in reward expectation and prediction error in PD patients with comorbid impulse control disorder
Objective: To study EEG oscillatory activity associated to reward prediction error in Parkinson’s disease (PD) patients with impulse control disorders (ICD) and determine how dopaminergic…Muscle Ultrasound Comparison Between Early And Intermediate Onset Friedreich’s Ataxia
Objective: Background: Early-onset Friedreich’s Ataxia (FA) concerns a classic pediatric phenotype (p-FA, starting before 18 years of age), characterized by relentlessly progressive ataxia and (cardio)myopathy.…Movement and postural control in focal dystonia subjects measured using surface electromyography
Objective: To explore the difference in muscle activation during a postural versus movement control task in patients with focal dystonia. Background: Co-contraction of agonist and…Temporal discrimination threshold in musician’s dystonia – an endophenotype?
Objective: To compare the temporal discrimination threshold (TDT) between musician's dystonia (MD) patients and healthy controls, and between dystonic and non-dystonic fingers of musicians with…Local field potential changes during sleep in the PSA of patients with essential tremor
Objective: To investigate changes in local field potential (LFP) activity of the posterior subthalamic area (PSA) in patients with essential tremor (ET) during wakefulness and…The utility of electrophysiological tests in the differentiation of upper limb tremor in young-onset patients
Objective: To explore the diagnostic utility of neurophysiologic tests in young-onset patients who present primarily with upper limb action tremor. Background: In young-onset patients, isolated…Closed loop spinal cord stimulation restores locomotion and desynchronizes corticostriatal beta oscillations
Objective: To test if closed loop Spinal Cord Stimulation (SCS) could be used to restore locomotion in a 6-hydroxydopamine (6-OHDA ) rodent model of Parkinson's…Long-term and dopamine dependent dynamics of subthalamic nucleus local field potentials in Parkinson’s disease
Objective: Using a new deep brain stimulation (DBS) pulse generator device that can record local field potentials (Activa PC+S, Medtronic Inc.), the current experiment investigated…
