Today’s computers use vast amounts of energy to do tasks that a living brain can achieve much more efficiently. So scientists are trying to create organic computers that can function at low energy levels.

A start-up on the shores of Lake Geneva is building computer networks using human brain cells, which could transform Artificial Intelligence systems.

It’s the latest foray into the field of ‘bio-computing’, also known as wetware.

RAZOR’s Amelia Hemphill visits the FinalSpark lab in Switzerland to find out more about how the brain organoids are grown and trained.

Each organoid is made up of about 10,000 neurons, or brain nerve cells grown from stem cells. These small spheres, approximately 0.5mm in diameter, are kept alive in incubators at near body temperature. They are then connected to tiny electrodes allowing for communication and training.
