INCF welcomes the Improving Neuroimaging Data for Sharing (INDoS) COST Action to Neurostars, its community-driven question-and-answer platform for neuroscience. INDoS brings together researchers and experts across Europe to improve the quality, standardization, and sharing of human neuroimaging data, including MRI, EEG, and MEG. Through Neurostars, INDoS participants can exchange technical knowledge, discuss challenges, and access expertise from the broader neuroinformatics community. This collaboration strengthens Neurostars as a shared resource for research communities working to make neuroscience data more FAIR, interoperable, and reusable.
