The International Neuroimaging Data-Sharing Initiative (INDI) provides multiple neuroimaging datasets hosted by the Child Mind Institute. Raw and preprocessed data includes structural MRI, functional MRI, Diffusion Tensor Imaging, and Electroencephalogram (EEG) for human and non-human primates. The data is shared under the ODC-By v1.0 license for imaging data and BSD 3-Clause for CPAC.
An EEG dataset published on Kaggle. The dataset likely contains recordings of brain electrical activity. Specific details on the number of subjects, recording parameters, and collection methodology are not provided in the available metadata.
739 licensed athletes from Çanakkale province participated in a study on psychological performance. Data includes responses from 413 men and 326 women aged 18-35, with 406 in team sports and 333 in individual sports. The research used scales measuring mental well-being, psychological performance, optimism, and pessimism.
This experimental replication dataset, produced by Eric Kramon for Perspectives on Politics, examines the effects of deliberative discussion on affective polarization in Honduras. The study utilizes a randomized design where participants were assigned to defend either their own policy perspectives or out-partisan viewpoints to measure changes in partisan animus. Data collection concluded with a final update in March 2026.
Omega EEG v9 is a dataset of electroencephalography (EEG) recordings, published on Kaggle. The dataset's specific content, scale, and collection details are not provided in the available metadata. Further verification of the data's origin, size, and structure is required after download.
EEG recordings likely capture brain activity related to motor tasks. The dataset is hosted on Kaggle, but its specific collection methodology, size, and authorship are not detailed in the provided metadata. Further details about the number of subjects, recording channels, and task specifics require inspection of the actual data files.
The Baby Connectome Project provides manually curated infant brain segmentations and accompanying T1-weighted and T2-weighted MRI images. The dataset covers participants aged 1 to 9 months and is hosted by the Masonic Institute for the Developing Brain (MIDB) Open Data Initiative. Data is stored in NIfTI format on AWS S3 under a CC-BY 4.0 license.
FINAL Bench is a functional metacognitive reasoning benchmark for Large Language Models containing fewer than 1,000 records, released by FINAL-Bench in early 2026. It shifts evaluation from final-answer accuracy to measuring an AI's ability to identify knowledge gaps and perform error recovery.
Kaggle hosts an EEG Movement Imagery Database. The dataset likely contains electroencephalogram recordings related to imagined or executed movements. Its specific size, collection details, and authorship are currently unknown.
Over 86% of participants in the MIDUS II longitudinal study completed the Brief Test of Adult Cognition by Telephone (BTACT), creating a cognitive dataset with unprecedented age, gender, SES, education, and geographic diversity. The data was collected from 2004 to 2006 by researchers at the University of Wisconsin–Madison, led by Carol D. Ryff, to examine links between biopsychosocial factors and cognitive performance across adulthood.
A high-resolution vector shoreline dataset for Lake Superior between Chequamegon Bay and Misery Bay, compiled from imagery by the National Oceanic and Atmospheric Administration. The data is structured for GIS use and follows the NGS C-COAST attribution scheme, influenced by international hydrographic standards. This resource is part of the NOAA Shoreline Mapping Program.
Megatruth_SS_test is a dataset hosted on Kaggle. Its platform tags indicate it is likely a test set for machine learning tasks. The dataset's specific content, size, and origin are not detailed in the available metadata.
