In addition, the location of alpha 2-adrenoceptor and opiate binding sites in consecutive sections of rat lumbar cord was investigated using in vitro autoradiography with selective ligands, and it was demonstrated that both opiate and alpha 2-receptor types are present within the same superficial layers of the dorsal horn of the same animal.

Because decerebration did not alter the depression due to clonidine, and intraventricular (but not intrathecal) administration of oxymetazoline mimicked the effect of clonidine, the depressant effects of alpha 2-adrenergic agonists are mediated through alpha 2-adrenergic receptors localized in the brainstem.
Localization (localized) of alpha 2-adrenergic in brainstem associated with medulla, depression, agonist, intrathecal and clonidine
