The Circuit Motif as a Conceptual Tool for Multilevel Neuroscience.

abstract：:For several decades, the reactive gliosis that occurs after an injury to the CNS has been considered one of the major impediments to axonal regeneration. Nevertheless, recent studies have suggested that in certain conditions, reactive astrocytes may provide a permissive substratum to support axonal regrowth. The impor...
