FRACTIONAL ANISOTROPY OF THE FORNIX AND HIPPOCAMPAL ATROPHY IN ALZHEIMER’S DISEASE
Frontiers in Aging Neuroscience, 2014 Decrease in the directionality of water diffusion measured with fractional anisotropy on diffusion tensor imaging has been linked to loss of myelin and axons in the white matter.

Kurtosis fractional anisotropy, its contrast and estimation by proxy [PDF]
Scientific Reports, 2016 AbstractThe diffusion kurtosis observed with diffusion magnetic resonance imaging (dMRI) may vary with direction. This directional variation is summarized in the scalar kurtosis fractional anisotropy (KFA). Recent studies suggest that kurtosis anisotropy offers microstructural contrast not contained in other commonly used dMRI markers.

Microscopic Fractional Anisotropy Detects Cognitive Training-Induced Microstructural Brain Changes. [PDF]
Tomography, 2022 Cognitive training-induced neuroplastic brain changes have been reported. This prospective study evaluated whether microscopic fractional anisotropy (μFA) derived from double diffusion encoding (DDE) MRI could detect brain changes following a 4 week cognitive training.

Myelin water fraction in relation to fractional anisotropy and reading in 10-year-old children [PDF]
Brain Structure and Function, 2021 Abstract Diffusion-weighted imaging studies have repeatedly shown that white matter correlates with reading throughout development. However, the neurobiological interpretation of this relationship is constrained by the limited microstructural specificity of diffusion imaging.

Fractional Anisotropy changes in Parahippocampal Cingulum due to Alzheimer’s Disease [PDF]
Scientific Reports, 2020 AbstractCurrent treatments for Alzheimer’s disease are only symptomatic and limited to reduce the progression rate of the mental deterioration. Mild Cognitive Impairment, a transitional stage in which the patient is not cognitively normal but do not meet the criteria for specific dementia, is associated with high risk for development of Alzheimer’s ...

Condensation of magnons and spinons in a frustrated ladder [PDF]
, 2006 Motivated by the ever-increasing experimental effort devoted to the properties of frustrated quantum magnets in a magnetic field, we present a careful and detailed theoretical analysis of a one-dimensional version of this problem, a frustrated ladder ...
