Some efferent connections of the nucleus medialis dorsalis. An experimental study in the cat

This is the authors' abstract. We don't add key points for this paper.

Single unilateral electrolytic lesions were placed stereotaxically at different loci in the nucleus medialis dorsalis of the cat. The modified Nauta‐Laidlaw silver method for the study of degenerating axons was used. Five animals with satisfactory lesions and staining qualities form the basis of this report. The nucleus medialis dorsalis in the cat sends efferent fibers to gyrus proreus, orbitalis, sigmoides anterior and genualis; also to the globus pallidus and putamen and to other thalamic nuclei. The findings indicated wider areas of projection of the nucleus medialis dorsalis to the frontal cortex than has been previously reported for this species. We were unable to confirm efferent connections from the nucleus medialis dorsalis to the caudate and hypothalamus as reported by others.
