Abstract

Unilateral, focal cerebrocortical lesion (FCL) and associated spreading depression (SD) increase immediate-early gene (IEG) expression throughout the ipsilateral hemisphere. Noradrenergic transmission is involved in the regulation of basal- and stimulation-induced expression of IEGs in cerebral cortex; and is modulated by both injury and SD. The present study further investigated the association between the noradrenergic system and cortical adaptive responses, by examining basal and FCL(SD)-induced cortical IEG expression following acute treatment with alpha(1)-, alpha(2)- and beta(1/2)-adrenoceptor (AR) agonists or antagonists. Activation of alpha(1)-ARs by NVI-085, or beta-ARs by salbutamo..
