Our amazing brain

This is an anatomical-realistic 3D brain visualisation showing real-time activity (power and “effective” connectivity) based on EEG (electroencephalography) signals. Each colour represents power and connectivity in a different frequency band (theta, alpha, beta, gamma) and the gold lines are neural connections (white matter). The estimated information transfer between brain areas is visualised as light pulses flowing along the neural connections that connect the areas.

The main parts of your brain

The brain makes up only about 2 per cent of the human body, yet it is responsible for all body functions and consumes 20 to even 60 per cent of your energy. Learn more about the components of the human brain and one of its unique defence mechanisms, the blood-brain barrier.
