Abstract

Unilateral lesion of the locus coeruleus and the resultant norepinephrine depletion in the ipsilateral cerebrum alters the relationship between cerebral metabolic demands and local delivery of oxygen and substrates. This effect of norepinephrine depletion is demonstrated by slower recovery of the redox ratio of cytochrome a,a3 during increased metabolic demands induced by local cortical stimulation.
