In Fish, Brain Cells Regenerate

Recent research published in Current Biology shows that the brains of zebrafish have amazing regenerative properties. The work suggests that a specific type of brain cell grows back after it is destroyed, and becomes fully functional again. Adam Douglass, Ph.D., assistant professor of neurobiology and anatomy, is co-senior author on the study with Richard Dorsky, Ph.D., professor of neurobiology and anatomy. Douglass explains the research and talks about parallels between the regenerating cells in fish and the dopaminergic cells that are destroyed in Parkinson’s disease in humans.
