neonatal 6-hydroxydopamine ( 6-ohda ) treatment was used to destroy the noradrenergic nerve endings in rat cerebral cortex and thus give some insight into the development and regulation of alpha-adrenoceptor subtypes , which in turn provides information concerning the anatomical localization of alpha 1- and alpha 2-adrenoceptors .
