Revolutionary Living Computer Made of Human Brain Tissue

Amid fears that robots might replace humans, it may be machines that should worry about us. Swedish scientists have created the world’s first living computer, constructed from human brain tissue. This groundbreaking development leverages 16 lab-grown brain organoids, tiny clusters of human brain cells, to create a revolutionary bioprocessor.

These organoids, or mini-brains, send and receive information through neurons, much like a traditional computer chip. However, they use over a million times less energy than today’s digital processors. For comparison, a human brain uses just 10 to 20 watts of power to achieve the same processing speed and 1,000 times more memory than the world’s top supercomputers, which require 21 megawatts.

Developed by FinalSparks, a startup specializing in biological neural networks, the living computer marks a dramatic shift in computing technology. Dr. Fred Jordan, co-CEO of FinalSparks, notes that while the concept of using living tissue in computing is common in science fiction, this real-world application is unprecedented.

These organoids, cultured from stem cells, are painstakingly developed to form neuron-rich tissues that can perform complex tasks. They are trained using dopamine, mimicking the reward system of the human brain. Light exposure in specific regions of the organoid releases dopamine, reinforcing correct task performance.

To sustain these mini-brains, they are housed in a microfluidic incubator that provides essential nutrients and maintains body temperature. This setup ensures a stable, bacteria-free environment for the organoids, which live and function for about 100 days before being replaced.

Dopamine doses are used to teach the organoids; when they perform well, they are rewarded with a stream of the neurotransmitter.

The organoids’ ability to perform computing tasks in a way that resembles human cognition could have far-reaching implications, from energy-efficient data processing to breakthroughs in understanding the human brain and curing diseases.

FinalSparks is already collaborating with global universities through an online platform to test this novel technology. As the world grapples with energy crises and the rise of AI, the living computer represents a promising solution for future cloud computing needs and data centers.

The company’s next focus includes testing and expanding this biocomputing technology and participating in the world's first biocomputing conference in Vienna. With the potential to revolutionize how we understand and utilize human brain tissue, the living computer is poised to lead the next wave of technological and scientific breakthroughs.

The Emergence of Brain-Computer Interfaces

Brain-computer interfaces (BCIs) represent the cutting edge of technology, facilitating direct communication between the brain and external devices. These interfaces have historically been the subject of extensive research and development, aimed at providing solutions for medical conditions such as paralysis and neurodegenerative diseases. Today, the integration of brain-computer interface technology with lab-grown human brain organoids is pushing the boundaries even further.

What are Brain-Computer Interfaces?

BCIs are systems that enable direct interaction between the brain's neural signals and a computer. They can decode brain activity to control external devices, offering potential applications in medical prosthetics, gaming, and even communication for individuals with disabilities. The core principle of BCI technology is the ability to translate neural signals into actionable commands for computers or other digital systems.

From Concept to Reality: Lab-Grown Human Brain Organoids

Lab-grown brain organoids, or mini-brains, are clusters of human brain cells cultured in a lab to mimic the structure and functionality of a real human brain. These organoids offer a unique opportunity to study brain development, disease, and now, brain-computer interactions.

A Marvel of Modern Science: The Living Computer Made from Human Brain Tissue

While many fear that robots will replace humans, the real revolution might be the machines needing to keep up with us. Swedish scientists have achieved the extraordinary: they’ve created the world’s first ‘living computer’ using human brain tissue. This breakthrough blends biology with technology, creating something truly groundbreaking.

Imagine 16 tiny brain organoids, or mini-brains, grown in a lab and connected to form a powerful bioprocessor. These organoids, clusters of human brain cells, communicate and process information in ways that mirror a computer chip but with a fraction of the energy. Where a human brain uses only 10 to 20 watts of power, our best supercomputers, like the Hewlett Packard Enterprise Frontier, require 21 megawatts to achieve comparable processing speeds and memory capacity.

Developed by FinalSparks, a pioneering startup focusing on biological neural networks, this living computer symbolizes a stunning leap in how we understand and use brain tissue. Dr. Fred Jordan, co-CEO of FinalSparks, explains that while the concept of a brain-based computer is a staple of science fiction, its realization is a groundbreaking venture in reality.

These organoids, cultivated from stem cells, grow over a month to develop neurons capable of sophisticated tasks. They operate on a principle of reinforcement, receiving dopamine—a natural reward—when they perform tasks correctly. This dopamine is administered by light exposure, mimicking the brain’s own reward system.

To keep these mini-brains functioning, they are housed in a state-of-the-art microfluidic incubator. This device provides essential nutrients and maintains an optimal environment, free from bacteria and viruses, ensuring the organoids can thrive and perform for about 100 days. When they cease to function, new organoids are grown to take their place.

"Life in Life: The First-Ever Living Computer Made from Brains!"

The living computer’s potential is vast, from revolutionizing data processing and cloud computing to providing profound insights into human cognition and disease. Already, FinalSparks has launched an online platform allowing global researchers to experiment with this novel technology, and numerous universities have shown interest in its possibilities.

As we face a global energy crisis and the rise of AI, this living computer offers a glimmer of hope. Its efficiency could revolutionize energy-hungry data centers and AI applications, providing a sustainable solution for our technological needs. FinalSparks is actively engaging with the scientific community and will participate in the world’s first biocomputing conference in Vienna, poised to lead the next frontier of innovation.

The journey of this living computer doesn’t just promise technological advancement; it symbolizes the harmonious fusion of biology and technology. It stands as a testament to human ingenuity and the endless possibilities when science transcends the boundaries of what we once thought possible.
