The role of chondroitin sulfate proteoglycans in regeneration and plasticity in the central nervous system

CM Galtrey, JW Fawcett - Brain research reviews, 2007 - Elsevier
Chondroitin sulfate proteoglycans (CSPGs) consist of a core protein and glycosaminoglycan

RY Tsien - Proceedings of the National Academy of …, 2013 - National Acad Sciences
A hypothesis and the experiments to test it propose that very long-term memories, such as
fear conditioning, are stored as the pattern of holes in the perineuronal net (PNN), a …
