Enhanced CoRR-Mind Research Network

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. The MRN Repeat Resting Sample consists of 112 scans from 56 healthy subjects. Each subject completed two scan sessions, four months apart. Two anatomical and resting fMRI are provided for each subject. Subjects were asked to keep their eyes open and presented with a fixation cross during the functional scan. They were given the following instructions: “We are about to begin the rest task. For this task you will be asked to lie still and keep your eyes focused on the crosshairs while the machine is on. Do you have any questions?” Note: Not all subjects have test retest resting state data available.
