The Informatics Core is directed by Arthur W. Toga, Ph.D., Professor of Neurology at USC, and Director of the Laboratory of Neuro Imaging (LONI). This Core is responsible for de-identifying, archiving, and disseminating all clinical, biospecimen, genetic and imaging data including raw and processed MR and PET scans. The Informatics Core provides access to ADNI data via the Image and Data Archive (IDA) on LONI and shares information and resources with the wider research community.

Due to serious data quality concerns, all data with PTIDs containing the format 381_S_10### have been removed from the ADNI data repository. ADNI leadership strongly advises that data with these PTIDs not be used in any data analysis, submission of abstracts, or publications. Furthermore, ADNI leadership requests that any abstracts or papers which have been submitted using this data be appropriately revised due to concerns with data quality. More information click here.
