The disease is caused by the accumulation of abnormally shaped α - synuclein proteins in neurons, leading to particularly toxic effects in dopamine - releasing cells located in brain regions that control movement.

Cory Blaiss, then at the University of Texas Southwestern Medical Center, and her colleagues genetically engineered mice such that the researchers could selectively turn neurogenesis on or off in a brain region called the hippocampus, a ribbon of tissue located under the neocortex that is important for learning and memory.
