Multimodal MRI analysis of microstructural and functional connectivity brain changes following systematic audio-visual training in a virtual environment.

Recent work has shown rapid microstructural brain changes in response to learning new tasks. These cognitive tasks tend to draw on multiple brain regions connected by white matter (WM) tracts. Therefore, behavioural performance change is likely to be the result of microstructural, functional activation, and connectivity changes in extended neural networks.

Validation of the European visual field standards for driving: A driving simulator-based study.

Purpose: To determine whether we could establish evidence-based pass/fail criteria for perimetry in the context of the European visual field standards for driving.

Methods: This two-centre, cross-sectional study included participants with binocular visual field loss that had led to revocation of a group-1 driving licence. The participants underwent cognitive and binocular visual testing, including the European Driving Test (EDT), a perimetry algorithm that adheres to the European visual field standards.

Understanding anti-immigration sentiment spreading on Twitter.

Immigration is one of the most salient topics in public debate. Social media heavily influences opinions on immigration, often sparking polarized debates and offline tensions. Studying 220,870 immigration-related tweets in the UK, we assessed the extent of polarization, key content creators and disseminators, and the speed of content dissemination.
