Table 2. Radioligand Binding Densities Determined by Quantitative Receptor Autoradiography in adjacent tissue sections of Squirrel Monkey (Saimiri sciureus) Brain.

Specific binding was determined in autoradiographs of tissue incubated with [³H]WIN 35,428 (5 nM), [³H]SCH 23390 (0.5 nM) and [³H]YM 09151-2 (0.2 nM). Brain Region Abbreviations are found in the legend to Figure 4.
