Distribution of norepinephrine-containing neurons projecting to the parietal association cortex and spinal cord in the cat locus coeruleus

Distribution of neurons forming projections to the parietal association cortex and spinal cord in the cat locus coeruleus (LC) was investigated by means of horseradish peroxidase retrograde transport and catecholamine histofluorescence techniques.

Description
Summary:Distribution of neurons forming projections to the parietal association cortex and spinal cord in the cat locus coeruleus (LC) was investigated by means of horseradish peroxidase retrograde transport and catecholamine histofluorescence techniques. Neurons projecting to the parietal cortex were found to be located mainly dorsally within the LC. Labeled neurons were also identified in the midbrain reticular formation, pons, and medulla when applying horseradish peroxidase to the parietal cortex and spinal cord. It was concluded that the cat parietal association cerebral cortex, in common with the spinal cord, receives direct afferent inputs from the locus coeruleus and the reticular formation.
