Following injection of HRP into the LRN, labelled cells were found mainly within Rexed's laminae VII and VIII of the spinal cord, the contralateral red nucleus, the ventrorostral aspect of the contralateral fastigial nucleus and the contralateral anterior sigmoid and coronal gyri of the cerebral cortex. Animals with injections of tritiated amino acids placed within the pericruciate cortex, red nucleus or fastigial nucleus were processed for autoradiography. In a corresponding series of animals, electrolytic lesions were placed selectively into the above sources of reticular afferents, and terminal degeneration within the LRN was studied by light microscopy. An extensive input from the spinal cord was found to terminate predominantly on the ipsilateral side throughout the rostrocaudal extent of the LRN, except for a small ventromedial area of the rostral parvocellular division and a small rostromedial area of the magnocellular division. The cortical projection terminated diffusely within the middle one\u2010half of the contralateral magnocellular division, while the rubral projection terminated extensively within the contralateral subtrigeminal division and the dorsolateral region of the rostral magnocellular and neighbouring parvocellular divisions. The rubral projection did not overlap the cortical projection. The fastigial nucleus projected sparsely to the contralateral LRN, mainly to the medial aspect of the rostral two\u2010thirds of the magnocellular division, with less to the parvocellular and subtrigeminal divisions.<\/jats:p><jats:p>The LRN therefore receives spinal and supraspinal projections within at least its rostral one\u2010half, and these terminate within specific areas in a partially overlapping fashion, whereas the caudal one\u2010half is primarily a spinal receiving region. No convergence of the rubral and sensorimotor cortical projections was evident.<\/jats:p>","DOI":"10.1002\/cne.901970309","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T18:36:13Z","timestamp":1104604573000},"page":"477-502","source":"Crossref","is-referenced-by-count":49,"title":["A light microscopic investigation of the afferent connections of the lateral reticular nucleus in the cat"],"prefix":"10.1002","volume":"197","author":[{"given":"A.
