Beyond the physical, chemical, and mystical processes that occur in the brain, it is not entirely clear to anyone what is actually happening inside it. Some say the brain commands the body; others shout, "No, no! It’s the body that’s in charge of everything!" There are even those who think the brain is just a soft mass that, when well-cooked, makes for excellent delicacies. Thought, language, imagination, sensation, perception, balance, posture, breathing, heart rate rhythm, blood pressure, learning, memory… Phew, how does so much fit inside when the head is so small?

It is known that our brain weighs approximately 1.4 kg, which is about three times the weight of a chimpanzee’s brain and five times that of a lion's, and that it resembles a light grey cauliflower. The brain is plastic, meaning it is constantly changing, and this change is called plasticity. When we learn something new, new connections are formed in the brain, and these connections between neurons become stronger the more often signals pass through them. But Dentro da Cabeça (Inside the Head) there are also the nose and the mouth with a tongue inside… Oh, and the eyes too… Phew, the ears as well! So many things!

How are we going to fit all of this into a performance? It seems like an impossible task. Let’s get to work!
