Reliability of Neuroimaging and Neurophysiological Tremor Features in Parkinson's Disease
Movement Disorders, EarlyView.Abstract Background Tremor is one of the cardinal motor symptoms of Parkinson's disease (PD). Its severity can be quantified with clinical rating scales and neurophysiology. The pathophysiology of PD tremor involves activity in the cerebello‐thalamo‐cortical circuit (CTC), which can be quantified with concurrent accelerometry‐functional magnetic ...

Topographic Electrophysiological Signatures of fMRI Resting State Networks
PLoS ONE, 2010 fMRI Resting State Networks (RSNs) have gained importance in the present fMRI literature. Although their functional role is unquestioned and their physiological origin is nowadays widely accepted, little is known about their relationship to neuronal activity. The combined recording of EEG and fMRI allows the temporal correlation between fluctuations of

Molecular Tools to Study and Control Dopaminergic Neurotransmission With Light
Medicinal Research Reviews, EarlyView.ABSTRACT Dopaminergic neurotransmission is involved in several important brain functions, such as motor control, learning, reward‐motivated behavior, and emotions. Dysfunctions of dopaminergic system may lead to the development of various neurological and psychiatric disorders, like Parkinson's disease, schizophrenia, depression, and addictions ...

Resting-State Functional Connectivity in Autism Spectrum Disorders: A Review
Frontiers in Psychiatry, 2017 Ongoing debate exists within the resting-state functional MRI (fMRI) literature over how intrinsic connectivity is altered in the autistic brain, with reports of general over-connectivity, under-connectivity, and/or a combination of both.

Construction of embedded fMRI resting state functional connectivity networks using manifold learning
, 2020 We construct embedded functional connectivity networks (FCN) from benchmark resting-state functional magnetic resonance imaging (rsfMRI) data acquired from patients with schizophrenia and healthy controls based on linear and nonlinear manifold learning ...

Nonparametric Modeling of Dynamic Functional Connectivity in fMRI Data [PDF]
, 2015 Dynamic functional connectivity (FC) has in recent years become a topic of interest in the neuroimaging community. Several models and methods exist for both functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), and the results ...

Magnetic Resonance in Medicine, EarlyView.Abstract Purpose Isotropic submillimeter high‐resolution functional MRI (fMRI) facilitates noninvasive investigation of neuronal activities at the mesoscale level, including cortical columns and laminae. However, the task‐evoked functional activity becomes less detectable when using single‐shot echo planar imaging (EPI) with parallel imaging techniques

Examining resting-state functional connectivity in first-episode schizophrenia with 7T fMRI and MEG
NeuroImage: Clinical, 2019 Schizophrenia is often characterized by dysconnections in the brain, which can be estimated via functional connectivity analyses. Commonly measured using resting-state functional magnetic resonance imaging (fMRI) in order to characterize the intrinsic or
