Multimodal population brain imaging in the UK Biobank prospective epidemiological study
UK Biobank brain imaging is described and results derived from the first 5,000 participants' data release are presented, which have already yielded a rich range of associations between brain imaging and other measures collected by UK Biobanks.
Acquisition and voxelwise analysis of multi-subject diffusion data with Tract-Based Spatial Statistics
This protocol describes the MRI data acquisition and analysis protocols required for TBSS studies of localized change in brain connectivity across multiple subjects, and aims to solve crucial issues of cross-subject data alignment, allowing localized cross- subject statistical analysis.
Sequential MR imaging and proton MR spectroscopy in patients who underwent recent detoxification for chronic alcoholism: correlation with clinical and neuropsychological data.
Regression of brain atrophy and metabolic recovery occurs at an early stage after abstinence from chronic alcohol abuse, and the recovery of NAA/Cr is associated with improved performance on neuropsychological tests.
Meta-analysis of real-time fMRI neurofeedback studies using individual participant data: How is brain regulation mediated?
Individual prediction of cognitive decline in mild cognitive impairment using support vector machine-based analysis of diffusion tensor imaging data.
SVM analysis of DTI data provided highly accurate individual classification of stable versus progressive MCI regardless of MCI subtype, indicating that this method may become an easily applicable tool for early individual detection ofMCI subjects evolving to dementia.

A way is suggested to improve the interpretation of affected DTI data by including a co‐regressor which accounts for the empirical response of regions affected by the artifact, and that subsequent increases in TE can be avoided by employing parallel acceleration.

Analysis of global and local brain volume changes in a longitudinal two-timepoint study with T1-weighted MRI at admission and after short-term sobriety follow-up in 15 uncomplicated, recently detoxified alcoholics suggests that early brain recovery through abstinence does not simply reflect rehydration.
Pitfalls in fMRI
This work reviews some essential processes and assumptions of BOLD fMRI and discusses related confounds and pitfalls in fMRI – from the underlying physiological effect, to data acquisition, data analysis and the interpretation of the results including clinical fMRI.
Ventral Premotor Cortex May Be Required for Dynamic Changes in the Feeling of Limb Ownership: A Lesion Study

The results point to a role of PMv and its connections in mediating changes in the sense of limb ownership driven by multisensory stimulation.
