** 1000 Functional Connectomes Project (FCP) / International Neuroimaging Data-Sharing Initiative (INDI) Data Release Announcement ** RELEASE NAME: Multiplexed Imaging Pilot Test-Retest Dataset PROVIDER: Enhanced Nathan Kline Institute - Rockland Sample (NKI-RS) DATA TYPE: Resting State fMRI (TR = 645, 1400, 2500), Diffusion Tensor Imaging (137 directions/2mm isotropic) ANNOUNCEMENT: We are pleased to announce the release of a 24-participant multiplexed imaging test-retest pilot dataset, created to evaluate the cutting edge “fast TR” sequences recently developed by Feinberg et al., 2010 (PLoS ONE). These pilot data were generated in preparation for using the sequences in the Enhanced NKI-RS – a large scale imaging effort, recently funded by NIMH to deeply phenotype and image 1000 individuals between the ages of 6.0 and 85.0 years, over the next 4 years. Consistent with the model of the initial NKI-RS effort, all data generated will be shared prospectively via FCP/INDI on a weekly basis. Each of the following scans were obtained two times (one week apart) for each participant: - multiplexed resting state functional MRI (TR = 645/3mm isotropic; 10 min) - multiplexed resting state functional MRI (TR = 1400/2mm isotropic; 10 min) - standard resting state functional MRI (TR = 2500/3mm isotropic; 5 min) - multiplexed diffusion tensor imaging (137 directions/2mm isotropic; <7 min). Additionally, we provide the following scans: 1) breath-holding, 2) visual checkerboard stimulation (blocked design) and 3) eye movement calibration.
