This second edition updates the burgeoning field of regeneration in the Central Nervous System (CNS) from molecular, systems, and disease-based perspective. While the book covers numerous areas in detail, special emphasis is given to discussions of movement disorders such as Parkinson’s disease, Alzheimer’s disease, and spinal cord injury.

* Incorporates information gained from cutting-edge photomicroscopy techniques
* Includes current information on clinical trials
* Presents chapters on stem cells and other novel treatments for diseases of the CNS
