Well then it would have been remarkable find indeed, as few would expect neural configurations forming a perfect loop or having a single point of failure.

  Why not? Larger evolutionary structures do seem to have a single point of failure, e.g. the heart.

    One neuron dying off is much more probable than a fatal heart condition. Heart is a multi-cellar, regenerative organ which often recovers from substantial damage.
