Role of dopamine and GABA during subthalamic and pallidal deep brain stimulation: Evidence of dopamine release during subthalamic Deep Brain Stimulation
Objective: We recorded the single-unit activity of striatal cholinergic interneurons of healthy monkeys during high-frequency stimulation (HFS) of the subthalamic nucleus (STN) and globus pallidus…The evaluation of metabolic differences by using 18F-FDG-PET/CT in demented and non demented Idiophatic Parkinson’s disease patients
Objective: The objective of this study was to identify metabolic group differences between Idiopatic Parkinson's disease patients with dementia (PDD) and without dementia (PD), by…Subthalamic nucleus activity during virtual reality provoked lower limb freezing in a patient with Parkinson’s disease and freezing of gait
Objective: Record subthalamic nucleus activity in a Parkinson's disease patient with gait freezing while they perform a virtual reality walking task during DBS surgery. Background:…Apraxia in Parkinson’s disease
Objective: We aim to study apraxia in Parkinson's disease. Background: Limb apraxia is a cognitive motor disorder of skilled, purposive movements not caused by elementary…The small GTP-binding protein Rhes influences midbrain dopaminergic neurons: Behavioral and biochemical studies
Objective: Rhes is a small GTP-binding protein highly enriched in the striatum, developmentally regulated by thyroid hormone, and by dopamine (DA) innervation in adult rat…Attention to action: Common to both conversion (psychogenic) and Parkinsonian (neurogenic) motor speech disorders
Objective: To review and present a common abnormality --- attention to action--- underlying Parkinsonian and conversion speech disorders. Background: Conversion speech disorders are characterized by…A case of thalamic malignant glioma formation in a patient with STN-DBS for Parkinson’s disease
Objective: We present a case of development of malignant glioma (glioblastoma multiforme) in the area adjacent to electrostimulation zone in a patient with chronic STN-DBS,…Long term recordings of subthalamic ocillatory activity in patients with Parkinson’s disease
Objective: The aim of this study was to investigate the stability of beta oscillations (13 - 30 Hz) in the subthalamic nucleus (STN) of patients…In-vivo free-water imaging and functional connectivity in a knock-in mouse model of DYT1 dystonia
Objective: To examine in-vivo functional connectivity and free-water diffusion imaging in dystonic mutant Tor1a knock-in (DYT1) and wild-type (WT) control mice. We test the hypothesis…Comparative study of the substantia nigra echogenicity and 123-I ioflupane SPECT in patients with REM behavior disorder
Objective: To compare (1) the echogenicity of substantia nigra (SN) in subjects with idiopathic REM behavior disorder (iRBD) and healthy controls and (2) to determine…
