Abstract:
The distribution of SP receptors was studied both in the normal human brain and in the parkinsonian brain by means of tritiated SP. The highest levels of binding were found in the striatal areas and in the NbM. The distribution was similar to that found in laboratory animals in earlier studies. In PD the binding was significantly reduced in the NbM and parietal cortex as compared with controls. The level of SPLI was reduced in both parts of the SN, in the NbM, and in the GPi.
