Restoration of Function

Complete restoration of function after injury to the human central nervous system (CNS) could be achieved if nerve cells and their processes sprouted appropriately and developed functionally appropriate connections. Because such a sequence of events does not seem to occur in the adult human CNS (see Frank, this volume), it is of obvious importance to understand the reason and what can be done to effect its occurrence. At the same time, other approaches to the problem of restoring function cannot be neglected.
