So what we discovered is that if you cut it into three pieces and amputate the head and the tail and you just take this middle fragment, which is what you see here, amazingly, there is an electrical gradient, head to tail, that's generated that tells the piece where the heads and the tails go and in fact, how many heads or tails you're supposed to have.
Lo que descubrimos es que si lo cortas en tres piezas y amputas la cabeza y la cola y tomas el fragmento del medio que es lo que ves aquí, sorprendentemente, se genera un gradiente eléctrico, de la cabeza a la cola, que le dice a la pieza dónde van la cabeza y la cola y de hecho, cuántas cabezas o colas se supone debe tener.
