Integration of resting state functional MRI into clinical practice - A large single institution experience.

PLoS ONE, 2018
Functional magnetic resonance imaging (fMRI) is an important tool for pre-surgical evaluation of eloquent cortex. Classic task-based paradigms require patient participation and individual imaging sequence acquisitions for each functional domain that is ...

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Temporal Interference Stimulation Modulates Resting State Functional Connectivity of Motor Circuit in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Transcranial temporal interference stimulation (TIs) targeting the subthalamic nucleus (STN) is a novel noninvasive neuromodulation approach with potential to improve motor symptoms in Parkinson's disease (PD). However, its underlying neuroimaging mechanisms remain unclear.

Resting-state functional connectivity of orthographic networks in acquired dysgraphia

Frontiers in Psychology, 2015
Introduction. While task-based fMRI has been used extensively to study the functional neural networks that instantiate cognitive functions, there is increasing interest in analyzing the activity of the brain while it is not performing a task – in the ...

Detecting spatiotemporal nonlinear dynamics in resting state of human brain based on fMRI datasets

, 2008
In this work, a nonlinear dynamics method, coupled map lattices, was applied to functional magnetic resonance imaging (fMRI) datasets to examine the spatiotemporal properties of resting state blood oxygen level-dependent (BOLD) fluctuations ...

Distinct Brain Drivers and Shared Cerebello–Cortical Input in ADCY5 and SGCE Hyperkinetic Movements

Movement Disorders, EarlyView.
Resting‐state fMRI and effective connectivity revealed distinct cerebellar–basal ganglia–cortical interactions in ADCY5 (MxMD‐ADCY5) and SGCE (MYC/DYT‐SGCE) related movement disorders. The cerebellum modulated cortex directly in MYC/DYT‐SGCE, but indirectly via basal ganglia‐cerebellar projections in MxMD‐ADCY5, which also showed reduced subthalamic ...

Studying Sub-dendrograms of Resting-state Functional Networks with Voxel-wise Hierarchical Clustering

Frontiers in Human Neuroscience, 2016
Hierarchical clustering is a useful data-driven approach to classify complex data and has been used to analyze resting-state functional magnetic resonance imaging (fMRI) data and derive functional networks of the human brain at very large scale, such as ...

Electroencephalography‐Based Clustering Reveals Robust Neurophysiological Subtypes in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Parkinson's disease (PD) is clinically heterogeneous, with substantial variability in motor and cognitive features. Conventional clinical scales provide limited insight into underlying neural mechanisms and show poor longitudinal stability.
