...Chris Bresee; Jules Litman-Cleper; Cindy J. Clayton; Leah Krubitzer Introduction: The gray short-tailed opossum, Monodelhis domestica ( M. domestica ), is a widely used marsupial model species that presents unique advantages for neurodevelopmental studies. Notably their extremely altricial birth...

...R. Waltzer; G.F. Martin We have employed axonal transport techniques to study the organization of projections from the medullary reticular formation (RF) to the forebrain of the North American opossum. The results of retrograde transport studies using large injections of horseradish peroxidase (HRP...

... similar projections exist in a marsupial, we explored the GC layer of the cerebellar cortex of anesthetized Virginia opossums using in-depth microelectrode micromapping and juxtathreshold cutaneous natural stimulation techniques.We found: (1) Somatosensory projections to the GC layer exist throughout...

Plotted on frontal plane diagrams of the hypothalamus and preoptic area located 10.7-19.7 mm anterior to the interaural axis. Negative points are indi­ cated by small...

...Maxime Lemieux; Thérèse Cabana; Jean-François Pflieger We use opossums Monodelphis domestica to study the development of mammalian motor systems. The immature forelimbs of the newborn perform rhythmic and alternating movements that are likely under spinal control. The hindlimbs start moving...

...G.F. Martin; M.S. Beattie; J.C. Bresnahan; C.K. Henkel; H.C. Hughes The present report describes the results of experiment designed to study supraspinal systems in the American opossum by several techniques. The data indicate that although spinal fibers from the opossum motor-sensory cortex...

...J.L. Culberson; D.L. Kimmel This paper describes the spinal cord distribution of primary afferent fibers from forelimb and hindlimb in the North American opossum. Fibers entering the cord distribute to all ipsilateral laminae (I-IX) within their segment of entry, often have a small crossed...

...T.S. Gray; J.C. Hazlett; G.F. Martin Using the horseradish peroxidase technique on the North American opossum, we were able to locate the neurons within the dorsal column and lateral cuneate nuclei which innervate the cerebellum and thalamus as well as those within the dorsal column nuclei which...

...J. Coleman; W.J. Clerici Projections from visual thalamus to posterior cortex of the Virginia opossum revealed by retrograde transport of horseradish peroxidase show a specific and orderly pattern. The lateral geniculate nucleus projects only to cortical area 17, while a lateral sector...

...G.F. Martin; T. Cabana; R. Waltzer Rubral neurons innervating the spinal cord, the lateral brainstem and the inferior olivary nucleus have been identified in the North American opossum by the retrograde transport of horseradish peroxidase and fluorescent markers. Neurons which project to the spinal...

...G.F. Martin; R.P. Waltzer Labeled neurons were found in most reticular and raphe nuclei of the opossum''s medulla after horseradish peroxidase (HRP) injections into either the spinal cord or diencephalon. The labeling produced by spinal injections differed somewhat from that produced...
