  1. Are action potentials in vertebrate muscle essential for contraction? This study of #zebrafish lacking #SodiumChannel NaV1.4 reveals that NaVs are dispensable for #muscle contraction, so the need for muscle #ActionPotentials can vary between vertebrates @PLOSBiology plos.io/42EXQwx

  2. Why is neuronal repolarization during #ActionPotentials so uniform despite ~10x range in axonal diameter? Study shows that higher K+ currents in smaller #axons compensate for biophys constraints, resulting in size-independent trigger signals #PLOSBiology plos.io/3ZzJvzE
