And at some point, there's a threshold, and automatically, the animal switches to swimming. This is amazing. Just changing the global drive, as if you are pressing the gas pedal of descending modulation to your spinal cord, makes a complete switch between two very different gaits.
En un momento, hay un umbral, y automáticamente, el animal pasa a nadar. Es increíble. Sencillamente cambia la marcha, como si pisar el acelerador de la modulación descendente en la médula espinal, cambiara por completo entre dos marchas muy diferentes.
