摘要
Afferent projections to the dorsal pons of the rat have been studied using the horseradish peroxidase (HRP) technique. HRP injections were made in each of the following regions: the vicinity of the locus coeruleus (LC); the periventncular gray, medial to the LC; the medial parabrachial region, lateral to the LC; the ventral cerebellum, dorsal to the LC; and the pontine reticular formation, ventral to the LC. Because intracranial self-stimulation (ICSS) has been obtained in these regions, the afferents have been discussed in terms of their possible contributions to that behavior. Previous ICSS studies of the dorsal pons have focussed on the LC as playing a central role. Presently identified inputs to the LC include: the dorsal raphe nucleus: the ventrolateral periaqueductal gray: the pontine reticular formation: the areas that contain the pontine and medullary noradrenergic and adrenergic cell groups: the lateral hypothalamic area: the contralateral LC: the deep cerebellar nuclei: the ventrolateral and parafascicular thalamic nuclei: and the parabrachial regions of the pons and midbrain. © 1979.
