Mind over chatter: plastic up-regulation of the fMRI alertness network by EEG neurofeedback [PDF]

open access: yes, 2012
EEG neurofeedback (NFB) is a brain-computer interface (BCI) approach used to shape brain oscillations by means of real-time feedback from the electroencephalogram (EEG), which is known to reflect neural activity across cortical networks.

Altered spontaneous brain activity in chronic smokers revealed by fractional ramplitude of low-frequency fluctuation analysis: a preliminary study

open access: yesScientific Reports, 2017
Although a substantial body of previous functional magnetic resonance imaging (fMRI) studies have revealed different brain responses to external stimuli in chronic cigarette smokers compared with nonsmokers, only a few studies assessed brain spontaneous ...

Discrepant Views of Apathy in Patients and Caregivers: the Role of Cognitive Deficits in Parkinson's Disease

open access: yesMovement 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 ...

Brain Imaging Changes Following Deep Brain Stimulation Patients with Parkinson's Disease: A Literature Review

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's Disease (PD) is a progressive neurodegenerative disorder primarily characterized by motor symptoms such as tremors, rigidity, and bradykinesia. Structural brain changes, including atrophy in the midbrain, basal ganglia, and cortical regions such as the frontal and temporal lobes, are observed in advanced stages.

Preoperative Functional Connectivity Predicts Antiparkinson Drug Change after Deep Brain Stimulation

open access: yesMovement Disorders, EarlyView.
Abstract Background Deep brain stimulation (DBS) can effectively ameliorate motor symptoms in Parkinson's disease (PD), but patient outcomes remain variable. Clinical predictors lack reliability and only explain a small proportion of outcome variance, outlining a need for biomarkers that can enhance prediction accuracy.

Constipation Is Linked to Neuroinflammation in Early Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Constipation is a risk factor for the onset and accelerated progression of Parkinson's disease (PD), but the mechanisms underlying this association are unknown. Neuroinflammation in PD has been demonstrated in postmortem and neuroimaging studies; however, its relationship with constipation has not been investigated.

Functional Connectivity to the Cerebellum and Resting‐State Networks Predict Earlier Improvement of Dystonia Following Globus Pallidus Internus‐Deep Brain Stimulation (GPi‐DBS)

open access: yesMovement Disorders, EarlyView.
Early improvement of dystonia after globus pallidus internus‐deep brain stimulation (GPi‐DBS) is associated with stimulation of the globus pallidus externus‐subthalamic nucleus (GPe‐STN) fibers and the lenticular fasciculus. Functional connectivity to the cerebellar cortex and the limbic and default mode networks predict early improvement of symptoms ...

Multimodal Imaging Investigation of the Dentato‐Thalamo‐Cortical Pathway in Friedreich's Ataxia

open access: yesMovement Disorders, EarlyView.
Abstract Background Friedreich's ataxia (FRDA) is a spinocerebellar neurodegenerative disorder. The dentato‐thalamo‐cortical (DTC) pathway, an important cerebellar output involved in motor control, plays a crucial role in the neural mechanisms underlying ataxia symptoms in FRDA.
