When the first nerve cell fires the second it wires in new synapses and continues to fire the original synapses. When networks of nerve cells are involved, the networks that fire the most take nerve cells from those around them that are less active. When networks are inhibited from firing, more active neighboring networks take back nerve cells. This process is the moment to moment reality of how the brain works and it is this principle that both causes pain networks to take cells from surrounding nerve networks and give back those cells if the surrounding networks are more active.
