Enhanced CoRR-Beijing Normal University 1

CoRR (Consortium for Reliability and Reproducibility) is committed to building an open platform for sharing resources of brain imaging science, aiming to provide standardized benchmarking datasets for test-retest reliability and reproducibility assessment in functional and structural connectomics research. To achieve this goal, CoRR integrated multimodal magnetic resonance imaging (MRI) datasets from multiple laboratories worldwide in 2014, based on which:1. Establish test-retest reliability and reproducibility standards for commonly used connectivity measurments using MRI methods;2. Clarify the reliability fluctuation range of the above measurements in different imaging stations and retesting schemes;3. Build a standardized retest MRI dataset to serve the validation of new connectivity measurements. Since 2024, an enhanced version of CoRR has been updated to enhance the neuropsychometrics on brain imaging assessments. Through standardized image preprocessing processes and the psychometric design expanded from a single retest to to 9 retests, and the raw MRI datasets have been aligned to a standard brain spaces. In addition, all preprocessed brain imaging data is open to the public through the Science Data Bank, providing standardized and unified data support and technical references. We believe that this open science practice will largely foster the transdisciplinary research of human neuroscience. This dataset included in this sample are a subset of the Connectivity-based Brain Imaging Research Database (C-BIRD) at BNU. This sample contains data from 57 healthy young volunteers (male/female: 30/27; age: 19-30 years) who completed two MRI scan sessions within an interval of approximate 6-weeks (40.94±4.51 days). All participants were right-handed and had no history of neurological and psychiatric disorders.The first session included two resting-state fMRI scans, T1, T2 and DTI. The two resting-state fMRI scans were at the beginning and the end of the session (~20 minutes apart). The second scan session included resting-state fMRI, T1 and DTI. Participants were instructed to rest and relax with their eyes closed and not fall asleep.Written informed consent was obtained from each participant, and this study was approved by the Institutional Review Board of the State Key Laboratory of Cognitive Neuroscience and Learning at Beijing Normal University.
