An Australian start-up based in Melbourne has unveiled a groundbreaking innovation — a “biological computer” composed of live human brain cells. The team at Cortical Labs introduced this cutting-edge technology, known as CL1, at a global technology conference in Barcelona. The CL1 system comprises hundreds of thousands of lab-grown neurons that exhibit learning capabilities in response to external stimuli.
Dr. Brett Kagan, the chief science officer at Cortical Labs, showcased the potential of CL1 during its launch, emphasizing its versatility for various applications. From disease modeling to drug testing, the biological computer opens up a realm of possibilities for research and development. Moreover, the team envisions leveraging these neural networks as a form of biological artificial intelligence, capitalizing on the inherent learning and decision-making abilities of human neurons.
While the concept of “biological AI” is intriguing, experts in the field caution against overstating the capabilities of systems like CL1. Dr. Kagan acknowledges the limitations of current technology but underscores the advantages of low power consumption and rapid learning exhibited by biological brains. Unlike traditional AI models that demand significant energy resources, CL1 operates efficiently with minimal power consumption, offering a unique approach to information processing.
The development of CL1, affectionately dubbed “Dishbrain,” marks a significant milestone in the convergence of biology and technology. By nurturing lab-grown neurons on specialized chips, researchers have unlocked the potential for these neuronal networks to acquire new skills and knowledge. While the system’s proficiency at playing Pong may seem rudimentary, it signifies a promising step towards harnessing the cognitive capabilities of biological components for practical applications.
Dr. Ernst Wolvetang, a prominent biologist engaged in stem cell research, underscores the complexity of neuronal networks and their implications for advancing scientific understanding. While Cortical Labs focuses on 2D neuronal networks, Wolvetang’s lab explores 3D brain organoids with enhanced cellular diversity. Collaborative efforts between the two research groups aim to synergize their expertise and explore the learning capabilities of different neural configurations.
As the field of biological computing advances, ethical considerations loom large. Dr. Silvia Velasco, a stem cell researcher, reflects on the ethical dimensions of manipulating brain cells in a dish, raising concerns about the potential emergence of consciousness or self-awareness in artificial neural networks. While the current technology remains far from replicating human cognition, stakeholders emphasize the importance of preemptively addressing ethical dilemmas.
Dr. Kagan acknowledges the ethical challenges inherent in manipulating live neurons for technological purposes. By collaborating with bioethicists and prioritizing responsible research practices, Cortical Labs aims to navigate the evolving landscape of biological computing ethically. The team’s focus on developing discreet neural systems underscores their commitment to leveraging brain cells as functional circuits without compromising ethical standards.
As the boundaries of computer technology expand to incorporate biological elements, the emergence of biological computers heralds a new era of innovation and exploration. With the potential to revolutionize industries ranging from healthcare to artificial intelligence, biological computing represents a frontier where human ingenuity and scientific discovery converge.
