In NeuroDataSets: A Comprehensive Collection of Neuroscience and Brain-Related Datasets

Cross-sectional Brain MRI Data Across Adult Lifespan

Description

This dataset, OASIS_cross_tbl_df, is a tibble containing a cross-sectional collection of MRI data from 436 individuals aged 18 to 96, obtained as part of the Open Access Series of Imaging Studies (OASIS). For each subject, 3 or 4 T1-weighted MRI scans acquired during a single scanning session are included. All participants are right-handed and include both men and women. Among the subjects over the age of 60, 100 have been clinically diagnosed with very mild to moderate Alzheimer’s disease (AD).
