Another fundamental object in WireWorld the diode --- a circuit element which will enforce the correct direction of travel on pulses --- which often prevents spurious signals from leaking into a region. The diode shown in the illustration will pass signals from left to right, but not in the opposite direction. Its relation to a barrier is evident upon inspection.
