D-1 dopamine receptors in the rat brain: a quantitative autoradiographic analysis.


The distribution of dopamine D-1 receptors has been determined in the rat brain by a quantitative in vitro light-microscopic autoradiographic method. The binding of [N-methyl-3H]-SCH 23390 to slide-mounted tissue sections takes place with characteristics expected of a substance that recognizes D-1 receptors. The binding is saturable, has high affinity, and… (More)
