Chronic Wallerian degeneration--an in vivo and ultrastructural study.

The rapid morphological responses of peripheral nerve fibres to a proximally situated crush in vivo were the subject of a previous communication (Williams & Hall, 1971). This paper describes the results of in vivo observation of the subsequent changes, particularly those of Wallerian degeneration, over a 60-day period. In vivo observation was also used to monitor various stages which were analysed ultrastructurally.
