Australian researchers have trained lab-grown brain cells on a silicon computer chip to play the ¡¯90s shooter game Doom and say they are just scratching the surface of what the neurons could be capable of doing.

It¡¯s the science-fiction work of biotech boffins at Cortical Labs, who researched and developed the technology that harnesses the workings of the brain¡¯s networking system.

Each so-called biological computer contains around 200,000 living human brain cells, grown from stem cells that were harvested from blood donations.
