TLDR
It is concluded that only muscle afferents terminate in the external cuneate nucleus of cat with the method of transganglionic transport of horseradish peroxidase.Abstract:
Muscular and cutaneous afferents from distal forelimb distributed to the cuneate and external cuneate nuclei have been demonstrated in cat with the method of transganglionic transport of horseradish peroxidase. Injections of the same tracer were also done in ganglia C7 to T6 to demonstrate the afferents to these two nuclei. It is concluded that only muscle afferents terminate in the external cuneate nucleus. Afferents from paw and forearm occupy sequential territories in the medial part of the nucleus, which are only partly exclusive. Afferents from individual flexor muscles of forearm occupy distinct sites but their distributions overlap with those of forearm extensor muscles. In the external cuneate nucleus, the, distributions of afferents from individual muscles constitute integral parts of a segmental representation. In the cuneate nucleus, cutaneous afferents are located dorsally and terminate over cells of the “clusters”. Muscle afferents are distributed in ventral regions and are topographically arranged. They terminate over “reticular” regions.read more

Movement-related inputs to intermediate cerebellum of the monkey
TL;DR: Asynaptic activation from the inferior cerebellar peduncle, in combination with histological localization of recording sites in granular layer or subcortical white matter, verified that mossy fibers produce a variety of waveshapes that are characterized by brief initial phases and relatively small amplitudes.

Central projections of the sciatic, saphenous, median, and ulnar nerves of the rat demonstrated by transganglionic transport of choleragenoid-HRP (B-HRP) and wheat germ agglutinin-HRP (WGA-HRP)
TL;DR: Motoneurons of the nerve were densely labeled by B‐HRP, including extensive regions of their dendritic trees, and the small population of labeled myelinated afferents mainly fell within the smaller ranges than within the larger ranges.

Output systems of the dorsal column nuclei in the cat.
TL;DR: The present study used single and double light microscopic retrograde tracing strategies in the cat to characterize the location and morphology of DCN neurons that project to different portions of the diencephalon, rostral mesencephalon and spinal cord.

Somatotopic organization of inputs from the hand to the spinal gray and cuneate nucleus of monkeys with observations on the cuneate nucleus of humans.
TL;DR: Central termination patterns of primary afferents from the hand and forelimb were studied following subdermal injections of HRP conjugates in macaque monkeys to postulate in detail the somatotopic organization of inputs to pars rotunda of humans.

TL;DR: Nineteen physiologically identified group Ia and five group Ib fibers at the L3 and L4 levels of the spinal cord originating from various hind‐limb muscles were intraaxonally injected with horseradish peroxidase (HRP) and the trajectories of the stained axons were reconstructed.
