Joseph Watson

Joseph Watson's lab is studying how synaptic function is altered in the age-related disorders, including Parkinson’s Disease and Alzheimer’s Disease. They use molecular/ biochemical and electrophysiological studies of synaptic function in vitro in mouse brain slices. The laboratory is also identifying the relevant brain targets of oxidative stress induced by pesticides and herbicides, which are environmental risk factors for Parkinson’s Disease.
