In particular, widespread «
synaptic pruning» — a sort of scaling down of connectors between neurons — reshapes the brain
as a child transitions to adulthood.
Specifically, converging lines of evidence suggest that mechanisms such
as oxidative stress and extracellular matrix (ECM) deficit may contribute to the functional impairment of PV neurons, leading to aberrant developmental
synaptic pruning of prefrontal cortex neural circuitry and hence a failure in the maintenance of
synaptic stability.
