Anatol Kreitzer, Salk Institute (IMAGE) Gladstone Institutes Caption Dr. Kreitzer and colleagues at the Salk Institute have used a sophisticated tracing technique -- known as the monosynaptic rabies virus system -- to assemble brain-wide maps of neurons that connect with the basal ganglia, a region of the brain that is involved in movement and decision-making. Developing a better understanding of this region is important as it could inform research into disorders causing basal ganglia dysfunction, including Parkinson's disease and Huntington's disease.
