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.
Errei o ângulo da câmara. Aquela só tem conteúdo amador, mas o que ela estava a dizer,  como puderam perceber, era sobre neurónios,  com as suas mãos assim, e ela estava a dizer que  os neurónios comunicam.
