The Georgetown Reading in Aging Neuroimaging Dataset (GRAND)

## The Georgetown Reading in Aging Neuroimaging Dataset (GRAND) The preprint desribing this dataset can be found here: https://www.biorxiv.org/content/10.64898/2026.05.18.725986v1 Description: The purpose of this study was to establish a normative database of visual word recognition and oral reading, as well as language-associated fMRI activations. This data also includes DTI and derived connectomes. The data is also appropriate for individual differences analyses. ## Summary This dataset contains raw and processed structural and functional MRI data, as well as DTI imaging and derived connectomes, from 110 healthy, neurotypical older adults. The fMRI task was the [Adaptive Language Mapping Task from Wilson et al., 2018](https://onlinelibrary.wiley.com/doi/full/10.1002/hbm.24077). Data was collected at the Center for Functional and Molecular Imaging at the Georgetown University Medical Center. ## Data Collection details: ## Acquisition details: Scanner: 3T Siemans MAGNETOM Prisma with 20-channel head coil. - T1w data: 176 sagittal slices; slice thickness = 1 mm; 1 mm3 voxels; field of view (FOV) = 256 mm; matrix = 256 x 256 mm; flip angle = 9º; generalized autocalibrating partial parallel acquisition = 2; repetition time (TR) = 1900 ms; echo time (TE) = 2.98 ms - FLAIR data: 192 sagittal slices; slice thickness = 1 mm; 1 mm3 voxels; FOV = 256 mm; matrix = 256 x 256 mm; flip angle = 120º; generalized autocalibrating partial parallel acquisition = 2; TR = 5000 ms; TE = 386 ms - Coplanar T2w: 48 slices; TR = 4010 ms; TE = 76 ms; slice thickness = 2.6mm with a 10% gap; 2.9 mm voxels; FA 150° - T2* data: 48 slices; TR = 794 ms; TE = 30 ms; slice thickness = 2.6 mm with a 10% gap; 2.9 mm voxels; FOV= 211 mm; matrix = 74 x 74; FA 50°; SMS = 4 - SE Fieldmap data - 48 slices; TR = 3130 ms; TE = 33 ms; slice thickness = 2.6 mm with 10% gap; FOV = 211; matrix = 74x74; FA = 90° - HARDI data: 74 axial slices; slice thickness = 2 mm; diffusion-weighted gradients: 81 directions at b = 3000, 40 at b = 1200, 7 at b = 0; 2 mm3 voxels; flip angle = 90º; phase encoding = anterior to posterior; partial Fourier = 6/8; FOV = 232 mm, matrix = 116 x 116 mm; TR = 4700 ms; TE = 82 ms; readout time = 61 ms; slice acceleration = 1
