Brain Network Oscillations During Gait in Parkinson's Disease

Doris D. Wang, Julia T. Choi
2020 Frontiers in Human Neuroscience  
Gait impairments are a hallmark of Parkinson's disease (PD), reflecting dysfunction of cortico-basal ganglia-brainstem circuits.  ...  Therefore, we propose that many gait dysfunctions in PD arise from derangements in brain network, and discuss potential therapies aimed at restoring gait impairments through modulation of brain network  ...  The ability to directly measure neural activity on the population level gives investigators a unique opportunity to study neuronal network functions and dysfunctions in disease states.  ...
