| Abstract: | Benzodiazepine receptor binding has been measured in soluble brain extracts with 3H-flunitrazepam as a ligand. Binding to soluble receptors is enhanced by GABAergic agonists with potencies and maximal augmentation essentially the same as on membrane bound benzodiazepine receptors. The GABA induced increase of binding to soluble receptors is reversed by the GABA antagonist bicuculline. |
