Most recently, we have been concentrating on the microcicuitry of the neostriatum. The neostriatum, most commonly refered to as simply the striatum, is the principal (although not only) input nucleus of the basal ganglia. Although most of the neurons in the striatum, 90-95% in rodents, are GABAergic projection neurons, there is a much smaller proportion of interneurons. One type uses acetylcholine as a neurotransmitter, and the others, comprising many distinct subypes, are GABAergic.
