The USC Stevens Neuroimaging and Informatics Institute (INI) is dedicated to understanding the structure and function of the human brain in all its staggering complexity—using imaging, genetics, behavioral and other measures to study the brain’s structure, function, development and change in both health and disease. During three decades of global advances in neuroimaging, the institute has amassed the world’s largest repository of images of healthy and diseased brains, as well as medical and genetic data from diverse populations around the globe.
