title: Differential labeling of the vestibular complex following unilateral injections of horseradish peroxidase into the cat and rat locus coeruleus.
abstract: Following unilateral injections of horseradish peroxidase into the cat and rat locus coeruleus (LC), bilateral retrograde labeling was evident in all 4 vestibular nuclei. In both species, the major contributions of LC afferents arose from the ipsilateral rather than the contralateral vestibular nuclei. Quantitative analysis in the rat has indicated that approximately 90% of the total vestibular-LC projections originated from the ipsilateral vestibular nuclear complex, with 10% from the contralateral. The frequency distribution was in the order of lateral greater than medial greater than superior greater than inferior vestibular nuclei.
