Footshock drives remodeling of perineuronal nets in retrosplenial cortex during contextual fear memory formation

•In most cortical areas Perineuronal nets (PNN) enwrap mainly GABAergic neurons, modulating synaptic plasticity.•Contextual fear conditioning (CFC) causes PNN expansion in some sensorial cortices.•After CFC the PNN in RSC remains expanded.•In the retrosplenial cortex (RSC), the footshock alone evoke...
