Title
Neuroscience: Fear net.
Abstract
The article highlights a study which determined that young rats that were trained to associate a sound with an electric shock can erase the fear memory when it is no longer relevant. It found that it was due to the development of the perineuronal net, an extracellular protein lattice that surrounds a subset of neurons as the rats mature. It examined that when an enzyme was used to dissolve the net in the Amygdala, adult rats can wipe off the memory of the shock as if they were young.
