Evaluation of monoaminergic receptors in the genetically epilepsy prone rat

Abstract
The intensity of sound-induced convulsions in the genetically epilepsy-prone rat (GEPR) was reduced in a dose related fashion by intracerebroventricular administration of dobutamine, (β1 agonist), terbutaline (β2 agonist) or phenylephrine (α1 agonist). BHT-920 (α2 agonist) did not cause a dose-related decrease in sound-induced convulsion intensity. Binding studies showed that whole brain α and β receptor densities (Bmax) were normal while the Kd was increased for the β ligand in GEPR brain.
