Recently, scientists from the Australian company Cortical Labs<\/strong> made headlines by connecting 200,000 living human neurons to a chip<\/strong>, enabling the neurons to play the classic video game, Doom<\/strong>. This groundbreaking project reflects the advancement in biotechnology and computational neuroscience.<\/p>\n In 2022, Cortical Labs successfully showcased how human neurons could play Pong<\/strong>. Following that demonstration, inquiries poured in about whether their technology could handle more complex games, leading them to confront the ultimate challenge: playing Doom. This first-person shooter game is not just about moving a character; it incorporates complex environments and enemy interactions.<\/p>\n Cortical Labs built their system on the CL1<\/strong>, the first commercial computer designed to utilize living human neurons in place of traditional silicon processors. Unlike human players, these neurons do not physically see the game screen. Instead, they interpret electrical signals<\/strong> emitted by the game, which reflect the in-game events. For instance, when a character takes damage or moves forward, those changes are converted into patterns of stimuli that the neurons can recognize.<\/p>\n Initially coping with the straightforward mechanics of Pong, the neurons gradually learned to play Doom despite the game’s intricate dynamics. Within less than a week, the biological network began to play, albeit at an amateur level. Cortical Labs\u2019 device is essentially a network of multiple CL1 units, each hosting its own set of neurons. These cells learn and adapt over time, improving their gameplay just like a human or animal would.<\/p>\n One of the breakthroughs of this project was the creation of an interface that facilitates real-time communication between the neurons and the game program. This connection is key in translating game events into electrical signal patterns understandable by the living neurons.<\/p>\n This advancement illuminates a future where biotechnology and computing intertwine. Professor Stefania Corti<\/strong> of the University of Milan noted that integrating active neurons with digital platforms opens new avenues for exploring learning mechanisms and neural plasticity. The insights gained could potentially revolutionize fields like neuroscience research<\/strong> and intelligent system development<\/strong>.<\/p>\n Interestingly, this concept of biological learning is not limited to neurons connected to a chip. A separate group of researchers was able to condition rats<\/strong> to play Doom, using a reward system that associated success in the game with a treat. By creating an immersive environment and progressively adapting their gameplay, these rats participated in a study that further emphasizes the inherent capabilities of living organisms to learn, even in virtual settings.<\/p>\n The exploration of using living cells in combination with digital devices signifies a monumental shift in our understanding of intelligence\u2014artificial or biological. As researchers like Cortical Labs continue to unravel the complexities of the brain, we are likely to witness further innovations that may forever alter the way we interact with technology, paving the way for intelligent systems borne from biological foundations.<\/p>\nThe Journey from Pong to Doom<\/h3>\n
