Diaminobenzidine (DAB) and tetramethyl benzidine (TMB) histochemical processing procedures were used to reveal the HRP reaction product.<\/jats:p><jats:p>In postnatal rats, individual muscle nerves were labelled to reveal the organization of muscle afferent projections to the motor nuclei. The terminals of muscle afferents were distributed widely across the dendritic arbors of motoneurons supplying the same muscles. No spatial segregation of the terminations of different populations of muscle afferents was discernable.<\/jats:p><jats:p>Afferents supplying different regions of the skin were labelled by applying HRP to the dorsal and ventral primary rami of the spinal nerves. Afferents in the dorsal rami projected to lateral portions of both the ipsilateral and contralateral dorsal horns while afferents in the ventral rami projected to the medial portions of both dorsal horns. The projections of the dorsal rami were shifted caudally relative to those of the ventral rami. This relationship reflects the fact that the regions of skin innervated by the dorsal rami are displaced caudally relative to those innervated by the corresponding ventral rami.<\/jats:p><jats:p>In fetuses, dorsal rami were labelled alone or in combination with ventral rami. These experiments disclosed the time course of development of the projections to different laminae of the spinal gray matter and revealed that afferents in the two primary rami project to appropriate regions in the ipsilateral and contralateral dorsal horns from the very outset.<\/jats:p>","DOI":"10.1002\/cne.902200105","type":"journal-article","created":{"date-parts":[[2005,5,27]],"date-time":"2005-05-27T20:33:28Z","timestamp":1117226008000},"page":"29-43","source":"Crossref","is-referenced-by-count":163,"title":["The development and postnatal organization of primary afferent projections to the rat thoracic spinal cord"],"prefix":"10.1002","volume":"220","author":[{"given":"Carolyn L.","family":"Smith","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,10,9]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4522(77)90074-4"},{"key":"e_1_2_1_3_1","volume-title":"The Comparative Anatomy of the Nervous System of Vertebrates, including Man","author":"Ariens\u2010Kappers C.
