Afferent connections of the anterior thalamus in rabbits.
This study was designed to determine whether axons of cholinergic dorsal tegmental neurons terminate on cells in the anterior thalamus in rabbits as in other species, and to localize projecting tegmental cells for future studies of their contributions to anterior thalamic learning-relevant neuronal activity. The distribution of retrogradely labeled neurons was examined following injections of wheat germ agglutinin horseradish peroxidase (WGA-HRP) centered in the anterior ventral (AV) thalamic nucleus. The results confirm past findings in rabbits indicating projections to anterior thalamus from the mammillary nuclei, the posterior cingulate cortex, presubiculum and postsubiculum. Demonstrated for the first time in rabbits were projections from the lateral dorsal and the pedunculopontine tegmental nuclei, locus coeruleus, dorsal raphe nucleus, Gudden's dorsal tegmental nucleus, pretectum and reticular thalamic nucleus.
