And what's interesting is that the salamander has kept a very primitive circuit, which is very similar to the one we find in the lamprey, this primitive eel-like fish, and it looks like during evolution, new neural oscillators have been added to control the limbs, to do the leg locomotion.
Lo interesante es que la salamandra conserva un circuito muy primitivo, muy similar al de la lamprea, ese pez parecido a una anguila primitiva, y parece que, durante la evolución, surgieron nuevos neuroosciladores para controlar las extremidades, para lograr la locomoción de las piernas.
