Autoradiographic studies on benzodiazepine receptor subtypes in the rat brain.

The technique of in vitro autoradiography which was developed by Kuhar and others was applied to the rat brain with use of 3H-flunitrazepam (flu) as a radioactive ligand. The cerebral cortex, hippocampus, substantia nigra and cerebellar cortex were rich in 3H-flu binding sites. To differentiate the benzodiazepine receptor (BZR) subtype, the authors used a… (More)
