Aging is associated with decreasing brain plasticity, especially after the closure of the critical periods of plasticity (a sensitive limited period in life of elevated brain plasticity). Some brain regions may be particularly affected by aging, such as prefrontal cortex (PFC), which has a key role in the organization of higherorder cognitive aspects, the executive functions, including attention, set-shifting, working memory, decision making, etc. Decline of plasticity in the PFC and the brain is attributed mainly to the appearance of a structure called perineuronal net (PNNs) which enwraps the cell body and dendrites of many classes of neurons. PNNs are extracellular matrix structures consisting of chondroitin sulfate proteoglycans, hyalur...
