The underlying mechanism of this paralysis is commonly thought to be selective damage affecting the upper-extremity nerve fibers in the pyramidal decussation.<\/jats:p>\n                  <jats:p content-type=\"fine-print\">The authors examined the anatomical basis of cruciate paralysis in six New World squirrel monkeys and two Old World cynomolgus monkeys. No evidence for a differential decussation of fore-limb and hind-limb fibers was found. Thus, there is no obvious anatomical explanation for cruciate palsy. The results do suggest two alternative explanations for cruciate paralysis: 1) selective damage to neural areas involving the internuncial cells, the central gray area, and the cuneate nucleus, or 2) injury to the ventral corticospinal tract.<\/jats:p>","DOI":"10.3171\/jns.1991.75.6.0935","type":"journal-article","created":{"date-parts":[[2009,5,19]],"date-time":"2009-05-19T12:25:34Z","timestamp":1242735934000},"page":"935-940","source":"Crossref","is-referenced-by-count":49,"title":["Decussation of hind-limb and fore-limb fibers in the monkey corticospinal tract: relevance to cruciate paralysis"],"prefix":"10.3171","volume":"75","author":[{"given":"Conrad T.
