05 The Brain | A Marvel
Laughing, grieving, speaking, singing, hearing, seeing, tasting, running, deciding, dreaming, loving ... With 100 billion nerve cells embedded in a highly complex network, the brain is a source of fascination and wonder. Our brain determines our perceptions, thoughts, feelings and actions, even our character traits. It depends on genetic predisposition and is influenced by environmental factors and learning processes. Imaging techniques are allowing us increasingly accurate insights into brain functions. However, the all-important question of how mental phenomena arise still remains unanswered. The reason for this is the extraordinary complexity of the excitation patterns that form in the highly networked brain.
