UCSF scientists have used a novel cell-based strategy to treat motor symptoms in rats with a disease designed to mimic Parkinson's disease. The strategy suggests a promising approach, the scientists say, for treating symptoms of Parkinson's disease and other neurodegenerative diseases and disorders, including epilepsy. The scientists transplanted embryonic neurons from fetal rats into an area of the adult rat brain known as the striatum, which integrates excitatory and inhibitory neurotransmitter signals to control movement...
