In a Blue Whale (Balaenoptera Musculus), Some Neurons Are Between

Essay

In a blue whale (Balaenoptera musculus), some neurons are between 50-100 feet long. This presents a technical obstacle - for example a USB cable can't be longer than about 20-30 feet long because the electrical signal becomes too diminished to be useful after that distance. How can action potentials travel these great distances (and in certain dinosaurs, even greater distances - up to 150 feet!) and still reliably convey information from one point to another?
