Because billions of neurons are packed into our brain, the neuronal circuits that are responsible for controlling our behaviors are by necessity highly intermingled. This tangled web makes it complicated for scientists to determine exactly which circuits do what. Now, using two laboratory techniques have mapped out the pathways of a set of neurons responsible for the kinds of motor impairments found in patients with Parkinson's disease.
