Cortical Labs CL-1: Australia's Biological Computer Powered by Human Brain Cells Ushers in New Era of Biocomputing

Australian Innovation: The Dawn of Biological Computing with Human Neurons

In a groundbreaking advancement for neuroscience and computing, Melbourne-based startup Cortical Labs has developed the CL-1, the world's first commercially available biological computer powered by living human brain cells. This hybrid system merges lab-grown neurons with silicon hardware, creating a platform that learns and adapts in ways traditional AI cannot match. Priced at around $35,000, the CL-1 is designed for researchers, offering unprecedented insights into brain function without relying on animal testing.

The technology stems from years of research, including the 2022 DishBrain project where neurons learned to play Pong, demonstrating goal-directed behavior. Today, the CL-1 represents a leap forward, with applications poised to transform drug discovery and disease modeling in Australian universities and labs.

Understanding the CL-1: How Human Neurons Meet Silicon

The CL-1 integrates approximately 800,000 lab-grown human neurons—derived from induced pluripotent stem cells (iPSCs) sourced from adult donors' skin or blood—directly onto a silicon chip featuring 59 electrodes. These neurons thrive in a nutrient-rich solution, supported by an onboard life-support system that regulates temperature, filters waste, and circulates fluids, keeping them viable for up to six months.

A key component is the Biological Intelligence Operating System (biOS), which simulates environments and facilitates closed-loop interactions. Electrical pulses represent data inputs, and the neurons' responses are read in real-time with sub-millisecond latency. This setup allows code deployment directly to the neural network, enabling it to process information, learn, and adapt organically.

Unlike rigid silicon AI, biological neurons exhibit plasticity, forming new connections and showing emergent behaviors, making the CL-1 ideal for studying dynamic neural processes.

Cortical Labs: From Melbourne Startup to Global Pioneer

Founded in 2019 by Hon Weng Chong, a medical doctor and software engineer, and Andy Kitchen, a computer scientist, Cortical Labs is headquartered in Melbourne. Chief Scientific Officer Brett Kagan, a neuroscientist, leads the science. The company's DishBrain milestone, published in Neuron, showcased neurons achieving Pong proficiency in minutes—far surpassing silicon deep learning in efficiency.

Backed by $10 million in funding from investors like Horizons Ventures and In-Q-Tel, Cortical Labs launched CL-1 at Mobile World Congress in Barcelona in March 2025. Recent demos include neurons playing Doom, highlighting learning capabilities.

The firm's mission: harness biocomputing's low energy and adaptability to revolutionize healthcare and AI.

Monash University and Australian Academia's Role in Biocomputing

Cortical Labs' ties to Australian higher education are strong, particularly with Monash University's Department of Neuroscience at Central Clinical School. Early collaborations funded by a $600,000 AUD National Intelligence and Security Discovery grant in 2023 explored merging human brain cells with AI, growing 800,000 neurons for advanced research.

University of Melbourne experts have also engaged, debating ethics of neuron chips. These partnerships position Australian universities as leaders in biocomputing, fostering PhD programs, postdocs, and faculty roles in neuroscience and biotech.

Energy Efficiency: A Game-Changer for AI and Research

CL-1 addresses AI's energy crisis: a rack uses 850-1,000 watts versus tens of kilowatts for equivalent silicon AI. Individual units consume less than a calculator, ideal for sustainable labs.

• Sample efficiency: Learns faster with less data.
• Scalability: Biology grows exponentially; millions of neurons feasible.
• Footprint: Compact for university wet labs.

This efficiency suits resource-constrained academic settings, enabling prolonged experiments.

Revolutionizing Drug Discovery and Disease Modeling

CL-1 excels in modeling epilepsy, Alzheimer's, and neuropsychiatric disorders. Test drugs on donor-specific neurons to uncover genetic links or restore function—e.g., antiepileptics improving learning in epileptic cultures. Its human relevance reduces clinical failures (90% for neuropsych drugs).

Australian unis can leverage CL-1 for personalized medicine, cell therapies, and cognition studies. Link to Cortical Labs CL-1 page for specs.

Ethical Advantages and Animal-Free Research

CL-1 offers ethically superior testing: human neurons replace animals, providing translatable data. Neurons from iPSCs avoid ethical sourcing issues; cultures are disposable post-6 months. Karl Friston calls it a 'brain in a vat' for safe experimentation.

Australian ethics boards favor such innovations, aligning with national research standards.

Cortical Cloud and Biological Data Centers: Scaling Up

Recent: Partnership with DayOne launches Cortical Cloud (120 CL1 units in Melbourne data center) and Singapore site (up to 1,000 units, initial validation at NUS Yong Loo Lin School of Medicine). Remote access democratizes biocomputing for global researchers.

This scales university research without hardware costs.
