The human brain, one of the most complex structures in the universe, has long been a central focus of scientific exploration, exploring how its various regions work together to generate thoughts, emotions, and actions. Modern neuroscience has clarified that the brain is not a homogeneous whole, but rather a collection of highly differentiated functional areas: the frontal lobe governs decision-making and language, the parietal lobe processes sensory information, the temporal lobe manages hearing and memory, the occipital lobe is responsible for vision, the insula regulates internal perception, and the cerebellum precisely coordinates motor balance. Understanding this "functional map" is the starting point for self-understanding. Our "Brain Model" exhibit transforms this abstract knowledge into a tangible experience through a giant interactive model measuring 5.2 meters in diameter and 3.1 meters high. Six interactive buttons corresponding to different brain regions surround the model.
