Floor square size predicts step count of 360° turns in PD patients with freezing
Objective: To determine the effect of floor square size on turning behavior in patients with PD. Background: Turning has been repeatedly shown to be the…Differential expression of cerebral dopamine neurotrophic factor (CDNF) in the hippocampus and in the striatum of LRRK-2 mutant rat model of Parkinson’s disease
Objective: The objective of our study was to characterize the behavioral phenotype of the transgenic LRRK-2 rat in the context of PD model and to…Diffusion tensor imaging (DTI) within the primate caudate nucleus marks dopaminergic (DA) and serotonergic (5-HT) lesions
Objective: To determine the best diffusion tensor imaging markers of dopaminergic and serotonergic lesions in the non-human primate. Background: DTI has received particular interest to…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…Reach-to-grasp impairments of both hands in individuals with Parkinson’s disease
Objective: To compare the reach-to-grasp (RTG) planning, kinematics and coordination of the less- (left) and more affected (right) hand in Individuals with Parkinson's disease (PD)…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:…F1 crossbreds of C57BL/6 and CD-1 mice demonstrate resistance to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced nigral neurodegeneration
Objective: To establish the neural basis of varying susceptibility to MPTP in MPTP resistant CD-1 mice, susceptible C57BL/6 mice and their crossbreds; simulating the variable…Involvement of peripheral immune system in the pathogenesis of Parkinson’s disease
Objective: To investigate the role of peripheral immune system in the pathogenesis of Parkinson's disease carrying LRRK2 risk variants. Background: Leucine-rich repeat kinase 2 (LRRK2)…Piper longum L. alkaloids inhibit lipopolysaccharide-stimulated microglial activation and protect nigral dopaminergic neurons
Objective: The ethanol-extracted alkaloids from the dry seeds of Piper longum L. (PLL) (family Piperaceae) PLA contain numerous compounds. We evaluate the potential of PLA…An exuberant cortical γb influences the unmasking and intensity of dyskinesia in 6-OHDA-treated freely-moving rats
Objective: To clarify the pathogenetic role of Beta band (βb) and Gamma band (γb) in 6-OHDA-treated freely-moving rats, by combining histochemical and electrophysiological investigations. Background:…
