Within the macrostructure of the island, two large 3D models of the brain show where the different areas responsible for higher functions are located: language, prassia (recognition of a simple logical sequence), intelligence (solving a puzzle), gnosia (recognition of objects, people, sounds, shapes). Visitors can also trigger these brain areas in their heads: in the macrostructure there are 4 interactive workstations offering activities on the activation of the areas shown in 3D models of the brain such as listening to an audio (language), recognizing a logical sequence (prassia), solving a puzzle (intelligence), recognizing objects (gnosia).
