Tartu museum opens brain exhibition inspired by Jaan Aru’s book

The University of Tartu Museum has opened an interactive exhibition space inspired by neuroscientist Jaan Aru’s book, exploring how the brain works and develops. The exhibition, reported by ERR, uses games to introduce children to concentration, learning and mental wellbeing.

Designed for families, the space lets visitors try activities at their own pace and consider how everyday choices shape their thinking. Klaus-Peeter Ladva, who plays the Mad Scientist, said a “free brain” is able to do interesting things and learn what a person chooses.

Visitors are encouraged to estimate the weight or length of objects before measuring them, showing children that making mistakes is part of being human. The playroom also includes spaces where visitors can take a break from stimulation. One, called the “boredom cave”, is intended as a place to simply sit and be bored, which Ladva said can help creativity emerge.

Instead of banning screen time, the exhibition invites children to build their ideal day from blocks and think about how smart devices affect attention. Ladva asked whether children would choose to spend three hours on a smartphone if they planned the next day in advance, saying this could show they are not entirely free to make those choices.

The exhibition will remain open as a permanent display at the museum.
