I got the camera angle wrong. That one is just amateur stuff, but what she was saying, as you could make out, was about neurons, with her hands were like that, and she was saying neurons communicate.
L'angolazione della videocamera è sbagliata. Quella è solo roba amatoriale, ma quello che diceva, se siete riusciti a capirlo, era riguardo ai neuroni, con le mani così, stava parlando di neuroni che comunicano.
