Abstract

When regeneration of the peripheral nerve takes place at an early stage of development, e.g. after nerve crush in newborn rats, the result of reinnervation is very poor. About 50 % of the neurons the axons of which had been crushed do not survive whether they be spinal motoneurons, or spinal ganglion cells (Romanes, 1946; Zelená and Hník, 1963; Schmalbruch, 1984; Jenq et al., 1987). In the reinnervated muscles, the number of muscle spindles is dramatically reduced and their structure is permanently altered (Hník and Zelená, 1961; Zelená and Hník, 1963; Soukup and Zelená, this volume).
