Serotonin and dopamine afferents to the rat locus coeruleus: a biochemical study after lesioning of the ventral mesencephalic tegmental-A10 region and the raphé dorsalis
Brain Res.

Abstract
The monoamine levels in the locus coeruleus (LC) were determined by HPLC following specific lesions of the ventral mesencephalic tegmental-A10 regions (VMT-A10) and raphé dorsalis (RD). Only lesions in the VMT-A10 area decreased the dopamine (DA) content, which strongly suggests that the projection from this region to the LC is of dopaminergic nature. Lesions of the RD increased DA metabolism in the LC and provoked significant decreases in the serotonin (5-HT) levels.
