An in-vivo study of BOLD laminar responses as a function of echo time and static magnetic field strength

Scientific Reports, 2021
Layer specific functional MRI requires high spatial resolution data. To compensate the associated poor signal to noise ratio it is common to integrate the signal from voxels at a given cortical depth.

Neuroimaging in Dementia [PDF]

Neurotherapeutics, 2011
Dementia is a common illness with an incidence that is rising as the aged population increases. There are a number of neurodegenerative diseases that cause dementia, including Alzheimer's disease, dementia with Lewy bodies, and frontotemporal dementia, which is subdivided into the behavioral variant, the semantic variant, and nonfluent variant ...

Clinical and cognitive improvement following full-spectrum, high-cannabidiol treatment for anxiety: open-label data from a two-stage, phase 2 clinical trial

Communications Medicine, 2022
Dahlgren et al. conduct an open-label phase 2 trial of a full-spectrum, high-cannabidiol product in 14 patients with moderate-to-severe anxiety. Anxiety is significantly reduced and the drug well-tolerated with no serious adverse events.

Using functional connectivity changes associated with cognitive fatigue to delineate a fatigue network

Scientific Reports, 2020
Cognitive fatigue, or fatigue related to mental work, is a common experience. A growing body of work using functional neuroimaging has identified several regions that appear to be related to cognitive fatigue and that potentially comprise a “fatigue ...

Neuroimaging in Dementia [PDF]

Seminars in Neurology, 2008
Although dementia is a clinical diagnosis, neuroimaging often is crucial for proper assessment. Magnetic resonance imaging (MRI) and computed tomography (CT) may identify nondegenerative and potentially treatable causes of dementia. Recent neuroimaging advances, such as the Pittsburgh Compound-B (PIB) ligand for positron emission tomography imaging in ...

Atypical connectivity in the cortico-striatal network in NF1 children and its relationship with procedural perceptual-motor learning and motor skills

Journal of Neurodevelopmental Disorders, 2022
Introduction Neurofibromatosis type 1 (NF1) is considered a model of neurodevelopmental disorder because of the high frequency of learning deficits, especially developmental coordination disorder.

The charm of structural neuroimaging in insanity evaluations. guidelines to avoid misinterpretation of the findings [PDF]

, 2018
Despite the popularity of structural neuroimaging techniques in twenty-first-century research, its results have had limited translational impact in real-world settings, where inferences need to be made at the individual level.

Functional near infrared spectroscopy (fNIRS) to assess cognitive function in infants in rural Africa [PDF]

, 2011
Cortical mapping of cognitive function during infancy is poorly understood in low-income countries due to the lack of transportable neuroimaging methods. We have successfully piloted functional near infrared spectroscopy (fNIRS) as a neuroimaging tool in
