A cognitive ontology dataset for neuroimaging studies of self-referential processing

For more detailed information on the dataset structure, version history, and other relevant details, please refer to the README.md file.The dataset has now been updated to Version 4. The first two versions included only 66 neuroimaging studies involving healthy participants, whereas Versions 3 and 4 were further expanded to include studies involving participants with a range of psychiatric disorders. In addition, the age range covered by the dataset has been broadened to include children, adolescents, and older adults.

In Version 4, the literature search strategy was further optimized by adopting broader and more targeted keyword combinations related to self-referential processing, thereby expanding the scope of the search and resulting in the inclusion of 26 additional studies. These newly included studies involve both psychiatric populations and healthy control participants performing self-referential tasks. Future versions will continue to incorporate studies examining other types of self-related stimuli, such as self-face recognition and autobiographical memory.
