The Welsh Advanced Neuroimaging Database: an open-source state-of-the-art resource for brain research

Abstract

Motivation: Advances in MRI have increased our understanding of the human brain but are frequently limited by single modality study designs. Combining data from multiple modalities/MR contrasts can enhance our understanding of the complex multi-scale neural relationships that underpin human behaviour. Goal(s): Our goal was to create an open-access multi-scale, multi-modal imaging database of the healthy human brain. Approach: The Welsh Advanced Neuroimaging Database (WAND) includes micro and macro-structural, functional and spectroscopic MRI, MEG and cognitive data from over 150 healthy volunteers. Results: WAND is free, open-source, organised using the Brain Imaging Data Structure (BIDS), and now available for download. Impact: The Welsh Advanced Neuroimaging Database takes steps toward democratising magnetic resonance research by making multi-modal, multi-scale neuroimaging data freely and easily available, enhancing opportunities for collaboration and development of novel analysis techniques, further progressing the field of neuroimaging.
