A new type of computer that combines regular silicon-based hardware with human neurons is now available for purchase.
The CL1, released March 2 by Melbourne-based startup Cortical Labs, is "the world’s first code deployable biological computer," according to the company’s website. The shoebox-sized system could find applications in disease modeling and drug discovery, representatives say.
Inside the CL1, a nutrient-rich broth feeds human neurons, which grow across a silicon chip. That chip sends electrical impulses to and from the neurons to train them to exhibit desired behaviors. Using a similar system, Cortical Labs taught DishBrain (a predecessor to the CL1) to play the video game Pong.
"The perfusion circuit component acts as a life support system for the cells – it has filtration for waste products, temperature control, gas mixing, and pumps to keep everything circulating,” Brett Kagan, chief scientific officer of Cortical Labs, told New Atlas.
The system uses just a few watts of power and keeps neurons alive for up to six months, according to the company’s website.
