Movement Disorders Clinical Practice, EarlyView.Abstract Background Apathy is a common early symptom of Parkinson's disease (PD), often co‐occurring with cognitive decline and associated with fronto‐striatal and mesocortico‐limbic dysfunctions. Discrepancies between self‐ and caregiver‐reported apathy have been preliminarily associated with cognitive impairments affecting patients’ awareness and ...

Resting-state functional magnetic resonance imaging for language preoperative planning
Frontiers in Human Neuroscience, 2016 Functional magnetic resonance imaging, fMRI, is a well-known non-invasive technique for the study of brain function. One of its most common clinical applications is preoperative language mapping, essential for the preservation of function in ...

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

Brain Networks Route Neurodegeneration Patterns in Patients with Progressive Supranuclear Palsy
Movement Disorders, EarlyView.Abstract Background Progressive supranuclear palsy (PSP) is a neurodegenerative disease driven by 4‐repeat τ pathology, which is thought to propagate across interconnected neurons. Objectives We hypothesized that interconnected brain regions exhibit correlated atrophy, and that atrophy propagates network‐like from fast‐declining epicenters to connected

Improving the Test-Retest Reliability of Resting State fMRI by Removing the Impact of Sleep
Frontiers in Neuroscience, 2017 Resting state functional magnetic resonance imaging (rs-fMRI) provides a powerful tool to examine large-scale neural networks in the human brain and their disturbances in neuropsychiatric disorders.

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 ...

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.

Movement Disorders, EarlyView.Abstract Background Visual hallucinations (VHs) are a common feature of Parkinson's disease (PD) believed to arise from disruptions to the functional architecture supporting sensory integration and attentional control. Across synucleinopathies, increased pathological burden in the amygdala and deficits in cholinergic modulation have been linked to VHs.
