in experiments designed to ask whether either of these inductions was mediated by specific types of adrenergic receptors , we found that the alpha 2- and beta-adrenoreceptors were involved in both responses , while the alpha 1-receptor played a role in mediating the yohimbine induction , but no detectable role in the solvent induction .
