New research by a team from the University of Michigan Medical School and the Pritzker Neuropsychiatric Disorders Research Consortium shows depression can sometimes mean too much of something: a protein called fibroblast growth factor 9, or FGF9. This image shows a rat hippocampus, a region of the brain critical for learning, memory and emotion.
The green cells show where researchers used an injected virus to block production of FGF9 and reduce anxiety-like behavior. The discovery goes against previous findings that depressed brains often have less of key components than non-depressed brains.Image credit: Elyse L.
