USC researchers have developed an approach that uses artificial intelligence to generate detailed maps that highlight differences in how distinct parts of the brain age. The new model also sheds light on how patterns of brain changes correlate with changes in cognitive function across the lifespan, according to a new USC study published in the journal Proceedings of the National Academy of Sciences.

A wearable fingertip patch could improve personalized care for people living with Parkinson’s disease by continuously tracking levels of Parkinson's medication through their sweat. The device operates using chemicals in this sweat — no batteries required. Its measurements were comparable to those obtained by standard laboratory blood tests.
