| Dark-field autoradiograms comparing the distribution of D1 receptor binding (A, C) defined by [3H]SCH 23390 in the presence of 1 mM ketanserin to D1 receptor mRNA (B, D) in the rat striatum and substantia nigra. While there is a good correspondence between D1 receptor mRNA expression and D1 receptor binding in the caudate-putamen (CPU), nucleus accumbens, and olfactory tubercle, there is a lack of correspondence in the substantia nigra (SN), where high levels of D1 receptor binding are observed and no D1 receptor mRNA. |
