Popis: A quantitative correspondence between nerve centers and their peripheral area of innervation has long been inferred from comparative and pathological studies. Many investigations have shown that by varying the mass or number of peripheral structures (1) a hypoplasia or hyperplasia, or (2) a hypotrophy or hypertrophy of their corresponding nerve centers results, indicating that a developmental relationship exists between that periphery and its innervating center. These changes in nerve cell number and size have been demonstrated in a variety of sites, including the spinal cord and spinal ganglia of chicks and amphibians (Piatt, 1948; Hamburger, 1955, 1958; Weiss, 1955). In addition to control of nerve cell number and size by the periphery, thyroid hormone has been demonstrated to affect, directly and indirectly, lateral motor column (LMC) cell number and size in the frog, Rana pipiens (Beaudoin, 1955, 1956; Kollros & Race, 1960; Race, 1961).
