traumatic brain injury alzheimer's disease
The image displays a TBI-affected brain’s white matter connectivity as inferred using diffusion tensor imaging and streamline tractography. The brain surface is rendered as a translucent layer to provide anatomical context for the streamline display. White matter connections and the brain surface are displayed using different colors across for the same subject. (Image/Kenneth Rostowsky)

Brain changes following traumatic brain injury share similarities with Alzheimer’s disease

Using MRIs and machine learning, USC researchers mapped comparable degenerative changes in both gray and white matter of the brain.

Multi-continental study examines brain scans of HIV-positive patients

By analyzing MRI data from patients around the globe, USC researchers are learning how HIV can lead to cognitive challenges, especially as the brain ages.
