Basal ganglia of brain. Coloured Positron Emission Tomography (PET) scan of a healthy brain, viewed at basal ganglia level. The colour-coded scan through this cerebral layer shows brain activity: from low (blue) to high (yellow). At centre and centre right are two pairs of basal ganglia (yellow ovals), nerve cell clusters deep in the cerebrum & upper part of the brainstem. The basal ganglia play a vital part in producing smooth, continuous muscular actions and in stopping and starting movement. PET scanning relies on a radioactive tracer injected into the bloodstream, to reveal metabolic activity in the brain.
