Pallidal DBS and pallidotomy alter cortical synchronization in Parkinson’s disease
Objective: To investigate electrophysiologic characteristics of sensorimotor cortical activity in patients with Parkinson's disease (PD) undergoing globus pallidus deep brain stimulation (GPi DBS) or radiofrequency…Recruitment of single subthalamic neurons for kinematic control of hand and feet movements employs different strategies
Objective: To understand single unit recruitment strategies for upper and lower extremity movements in the human subthalamic nucleus (STN), which is the main target for…Effectiveness of Levodopa responsiveness of Blink reflex recovery: An objective method to differentiate Parkinsonian syndromes
Objective: We attempted to find an objective tool by assessing the variability of levodopa induced change in the blink reflex recovery to differentiate Parkinsonian syndromes.…Increasing placebo response in Parkinson’s disease through apomorphine pre-conditioning
Objective: To see whether a placebo response requires pharmacological pre-conditioning with apomorphine. Background: Placebos have been found to affect the patient's brain in a number…Diffusion tensor imaging of the corticospinal tract differentiates Parkinson’s disease (PD) patients from controls
Objective: To asses white matter tractography of the corticospinal tract in PD patients. Background: Since the diagnosis of PD is still based on clinical assessment,…Diagnostic reliability of clinical symptoms in patients with incomplete manifestation of the triad of parkinsonism compared to 18F-DOPA PET-CT MRI imaging
Objective: To describe the diagnostic reliability of the triad of clinical symptoms compared to the uptake of 18 F-DOPA PET-CT fusion MRI scan. To compare…Brain mechanisms underlying visual processing in Parkinson’s disease
Objective: We used fMRI and a visual cognitive task to study brain mechanisms underlying visual processing at different cognitive loads in patients with PD and…Cerebellar GABA-A receptor activity is inversely correlated with gait speed in Parkinson’s disease
Objective: To investigate the relationship between regional cerebral expression of benzodiazepine receptors and gait speed in Parkinson's disease (PD). Background: Flumazenil is a short-acting intravenously…Combined effects of visual and auditory cues on gait initiation in Parkinson’s disease
Objective: To investigate the combined effects of visual and auditory cues on gait initiation and to investigate the correlation between the clinical rates of gait…Comparison of DAT scan, cardiac MIBG scintigraphy, and cerebrospinal fluid 5HIAA levels in Parkinsonian syndrome
Objective: To assess the associations of presynaptic dopamine transporter (DAT scan), cardiac 123I-meta-iodobenzylguanidine (MIBG) scintigraphy, and cerebrospinal fluid (CSF) levels of 5-hydroxyindole acetic acid (5HIAA)…
