Journal ArticleDOI
Intracortical Inhibition and Surround Inhibition in the Motor Cortex: A TMS-EEG Study.
Giorgio Leodori,Nivethida Thirugnanasambandam,Hannah Conn,Traian Popa,Alfredo Berardelli,Mark Hallett +5 more
TL;DR: The findings suggest that SICI and mSI modulate cortical excitability with shared inhibitory mechanisms, suggesting cortical facilitation associated with motor performance.
Journal ArticleDOI
Dynamics of Top-Down Control and Motor Networks in Parkinson's Disease.
TL;DR: In this paper, the authors investigated dynamic functional connectivity (dFC), during resting state functional magnetic resonance imaging, between sensorimotor network and top-down control networks in 36 PD patients (OFF medication, PD-OFF) and 36 healthy volunteers.
Journal ArticleDOI
Parkinson’s Disease Motor Subtypes Show Different Responses to Long-Term Subthalamic Nucleus Stimulation
TL;DR: The data confirms that PD is heterogeneous, and the findings support the idea that ART mainly involves the basal ganglia-thalamo-cortical pathway, whereas TDT involves a different circuit, likely the cerebellar-thalamon-cORTical pathway.
Journal ArticleDOI
Positron emission tomography [15O]water studies with short interscan interval for single-subject and group analysis: influence of background subtraction.
Jolanta Chmielowska,Robert C. Coghill,Jose-Marie Maisog,Richard E. Carson,Peter Herscovitch,Manabu Honda,Robert Chen,Mark Hallett +7 more
TL;DR: Examination of how subtraction of residual radioactivity from the previous injection compared to nonsubtraction in a PET short interscan interval (6 minutes) study affects single-subject and group data analysis using a motor activation task found excellent agreement between activation maps obtained from corrected and uncorrected data sets.
Journal ArticleDOI

TL;DR: It is suggested that the parietal multimodal sensory association region could have an aberrant downstream influence on the fine motor control network in writer's cramp, which could be artificially restored to its normal function.
