Motor Network Physiology
The brain networks controlling movement are complex, involving multiple areas of the brain. Some neurological disorders, like Parkinson's disease (PD) and essential tremor (ET), cause abnormalities in these brain networks. Deep brain stimulation is a treatment that is used to treat these types of neurological diseases and is thought to …
Udall Project 2 Aim 2A&C
This protocol will leverage the novel (on-label, FDA-approved) local field potential measuring capability of the Medtronic Percept™ PC or RC DBS system to study the effects of globus pallidus internus, globus pallidus externus (GPi, GPe), and subthalamic nucleus (STN) DBS on: the wash-out and wash-in dynamics of motor behavior and …
Movement Error-processes and Sensorimotor Adaptation in Parkinsonian Patient
The aim of the present project is to document the relationship between the behavioral deficits and the electrophysiological anomalies observed in PD patients in tasks involving motor adaptation to visual or mechanical perturbations.
Drug Discovery for Parkinson's with Mutations in the GBA Gene
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate Parkinson's disease research and drug development by using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, …
Exploring the Gut-Brain Axis in Ageing and Neurodegeneration
Neurodegenerative diseases are a major health concern due to their growing societal implications and economic costs. The identification of early markers of pathogenic mechanisms is one of the current main challenges. The gut-brain axis has become a primary target because of its transversal role across the neurodegenerative spectrum and its …
International Validation of Two Non-motor Scales in PD (NFS and SPARK)
The goal of this project is to develop the international validation of two new rating scales, the Neuropsychiatric Fluctuations Scale (NFS) and the Shame in PARKinson's disease (SPARK) Scale, in order to improve the understanding of the extent and severity of non-motor symptoms in Parkinson's disease (PD).
Udall Project 1 Aim 4
By defining the strength and direction of connectivity patterns at rest and during movement across the basal ganglia-thalamocortical (BGTC) network we will characterize the role of individual circuits in motor performance and cognitive function, paving the way for future development of optimization algorithms for DBS that take advantage of this …
Parkinson's Disease Biomarkers in Nerve Cells in the Gut
Parkinson's disease affects all the nerve cells in the body, including the ones in the gut. The gut contains its own nervous system, the enteric nervous system, and can be thought of as a "second brain". This second brain can reflect what is going on in the actual brain. This …
Localized Analysis of Normalized Distance From Scalp to Cortex and Personalized Evaluation (LANDSCAPE)
Scalp to cortex distance (SCD), as a key technological parameter of brain stimulation, has been highlighted in the guidelines of non-invasive brain stimulation. However, in the context of age-related brain changes, the region-specific SCD and its impact on stimulation-induced electric field in different types of neurodegenerative diseases remain unclear.
Investigating Complex Neurodegenerative Disorders Related to Amyotrophic Lateral Sclerosis and Frontotemporal Dementia
Background:Neurodegenerative disorders can lead to problems in movement or memory. Some can cause abnormal proteins to build up in brain cells. Researchers want to understand whether these diseases have related causes or risk factors.Objective:To test people with movement or thinking and memory problems to see if they are eligible for …
