When comparing tetrodotoxin found in puffer fish and batrachotoxins from poison dart-frogs, the former had no effect on a neurons resting potential but completely stopped its action potential, whereas the later toxin immediately initiates depolarization of a neuron but prevents repolarization. Can your group hypothesize how these toxins affect the nerve transmission differently?
