Anisotropic Anomalous Diffusion assessed in the human brain by scalar invariant indices

, 2010
A new method to investigate anomalous diffusion in human brain is proposed. The method has been inspired by both the stretched-exponential model proposed by Hall and Barrick (HB) and DTI.

Impact of Mood States on the Development of Learning Strategies of University Students

European Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT Moods and the development of learning strategies are intrinsically linked due to the influence of emotional and cognitive factors. When students experience positive moods, such as joy, information processing and retention are facilitated, but negative moods, such as stress, anxiety or hostility, can interfere with concentration and academic ...

Diffusion Kurtosis Imaging of Substantia Nigra Is a Sensitive Method for Early Diagnosis and Disease Evaluation in Parkinson’s Disease

Parkinson's Disease, 2015
Background. To diagnose Parkinson disease (PD) in an early stage and accurately evaluate severity, it is important to develop a sensitive method for detecting structural changes in the substantia nigra (SN). Method.

Diffusion Kurtosis Imaging and Radiomics in Diffuse Axonal Injury

Radiology - Practice
This study aimed to assess the feasibility of radiomic features derived from diffusion kurtosis imaging (DK MRI) in identifying microstructural brain damage in diffuse axonal injury (DAI) and predicting its outcome. We hypothesized that radiomic features, computed from parametric DK MRI maps, may differ between healthy individuals and those with trauma ...

White Matter Tract Alterations in Bipolar Disorder: A Systematic Review and Meta‐Analysis of Diffusion Tensor Imaging Studies

Brain and Behavior, Volume 16, Issue 5, May 2026.
This systematic review and meta‐analysis synthesizes diffusion tensor imaging evidence of white matter microstructural abnormalities in bipolar disorder. Across published studies, patients with bipolar disorder showed reduced fractional anisotropy in several major white matter tracts, including the corpus callosum, cingulum bundle, corona radiata ...

Velocity correlations in dense granular flows observed with internal imaging

, 2006
We show that the velocity correlations in uniform dense granular flows inside a silo are similar to the hydrodynamic response of an elastic hard-sphere liquid. The measurements are made using a fluorescent refractive index matched interstitial fluid in a
