Beneath the surface: What zebrafish can tell us about anxiety

One researcher has focused how genetics influence responses to stimuli that can trigger anxiety, and he's using zebrafish -- a tropical member of the minnow family named for the black stripes on their bodies -- to do so. His research team examines how fish with tweaked genes respond to different triggers compared to unmodified fish. The work could someday lead to better, more nuanced medications for anxiety disorders.
