This fascinating installation, the work of Berlin-based media artist Ulrich Malik and called "The World in Sounds" impressively illustrates the relationship between perception and memory. With 30 original sounds from around the world, visitors are taken on an exciting journey around the globe: How about a ride on the Trans-Siberian railway, or a stroll through a Bavarian forest? Those able to associate not only television images with these sounds but also own holiday experiences may even find certain smells or tastes coming to mind. How is this chain reaction created? Memories are made up of many small particles stored in different parts of the brain. If a certain area is activated, for example, a sound memory, the other areas are automatically stimulated too.

What tells you that you have an appetite for something in particular? How do you know that something is itching? How can you tell that you have a stitch in your side? All these sensations have to do either directly or indirectly with our sense of touch. We touch both inside and outside our bodies. In the Tactile Dome, a 30m² dark labyrinth, you will feel the world around us. At least five different receptor types are responsible for sensory impressions: One receptor registers heat, another cold, another reacts to light, another to touch. Finally, there are receptors that convey cell damage to the brain, which is when we experience pain. Which tactile location is connected to which receptor type? Find out for yourself!

The sense of smell is connected to the oldest part of our brain in evolutionary terms - a part that developed long before the speech centre: the brainstem. There is no direct connection between the nose and the speech centre. For this reason, it is often difficult to describe a smell. How would you explain, for example, the smell of a banana? It's almost impossible. For this reason the sense of smell is called the silent sense. And yet this sense is very important when it comes to evoking past feelings and long-lost memories. In the Scent Chambers, visitors can sniff different essences and discover which associations are awakened by them. The first scented column has an idyllic forest motif and gives off a floral smell. What do you associate with it? Leisurely strolls? Sore muscles? Hard-boiled eggs? Childhood? Everyone has different experiences in life and no life is identical to another, therefore everyone perceives scents differently.

The eyes are the mirror of the soul, and looking into the eyes of another human being is one of the most intimate forms of contact. Eye contact enables an instantaneous exchange of information. What does the gaze of another tell you? Just as fascinating as looking into the eyes of another is the eye itself.
Three simple but astonishing experiments allow visitors to gain an insight into the eye. How does my eye react to brightness? Why am I able to see the blood vessels in my own eyes? How can even individual blood cells become visible? Anyone who looks into an intensive blue light will see bright dots that flit back and forth. These are the tiny red blood cells of the retina. They bend the light and thereby become visible. This phenomenon can be observed at the blood cells exhibit. The blood cells even move in time to your heartbeat.
