Salk Institute Allen-AHA Organoid (IMAGE) Salk Institute Caption Salk awarded $19.2 million by the American Heart Association-Allen Initiative to study Alzheimer's and aging in the brain. This illustration shows a blood vessel traversing neurons and support cells called glia in a brain organoid, as recently described in research from the Gage lab. Improved 3D models of brain function can better approximate both health and diseases such as Alzheimer's. Credit Salk Institute Usage Restrictions with credit and related coverage.
