Who actually controls what we think and feel, how we move and how we speak? It all happens in our brain. It is the body's control centre - a bit like the cockpit in an aeroplane. The brain consists of billions of nerve cells that are interconnected.

When we learn something new, for example new vocabulary or how to do a handstand, the nerves in the brain also have to reconnect. Some connections also become more stable because we have learnt some things particularly well: Walking, for example, or eating with a knife and fork.

But how do the nerve fibres in our brain grow? And what substances does the body use to control this? And what happens, for example, if the brain is injured in an accident? In this lecture, we will find answers to these questions together.
