To facilitate scientific discoveries in the field of comparative neuroanatomy and brain evolution, we launched a collaborative project to develop repository of non-human primate brain images using ex vivo MRI as an open resource. As an initial attempt, we released a collection of structural MRI and diffusion tensor imaging obtained from postmortem brain samples, stored in the Japan Monkey Centre (JMC), were scanned using a 9.4 T MRI scanner and made available through the JMC collaborate research program. 
The expected significances of the JMC Primates Brain Imaging Repository include; (1) resource for comparative neuroscience research, (2) preservation of various primate brains including endangered species in a permanent digital form, (3) resource for optimizing method to scan large-sized fixed brains, and (4) references for veterinary neuroradiology. User-initiated research projects beyond these significances would also be anticipated.

The JMC Primate Brain Imaging Repository is operated in partnership by the JMC, Kyoto University, the Jikei University School of Medicine, Keio University School of Medicine, and the Johns Hopkins University School of Medicine, and is supported by JSPS KAKENHI Grant, JSPS Postdoctoral Fellowship for Research Abroad, and Brain/MINDS. Part of this work was supported by the Fakhri Rad Brite Star award from the Department of Radiology Johns Hopkins University School of Medicine.
