Axon Regrowth: The Neurobiology of Nerve and Axon Regeneration, originally published in 2008 and now fully revised-with a refocus on the central nervous system and axon regeneration-emphasizes the commonalities and differences with peripheral nerve regeneration. The book reviews the substantial problems of axon and nerve regeneration, including molecular mechanisms and the approaches that can be used to experimentally address new avenues. Both researchers and clinicians alike will consider this a valuable resource.
