“…This has led to a comprehensive investigation of neuronal compression including histological, electrophysiological and clinical examination of various animal and human models (DennyBrown & Brenner, 1944 a, b;Fullerton & Gilliatt, 1967 a, b;Anderson, Fullerton, Gilliatt & Hern, 1970;Ochoa, Fowler & Gilliatt, 1971Fowler, Danta & Gilliatt, 1972;Ochoa & Marotte, 1973;Gilliatt, 1980;Rydevik & Nordborg, 1980;Gelberman, Hergenroeder, Hargens, Lundborg & Akeson, 1981;Gelberman, Szabo, Williamson, Hargens, Yaru & Minteer-Convery, 1983;Powell & Myers, 1986;Lundborg, 1988;Dahlin, Shyu, Danielsen & Andersson, 1989;Olmarker, 1990). These studies have provided detailed information regarding the changes in nerve structure and function which follow compression, but have left doubts regarding the fundamental causes of such changes.…”
