Introduction
Imagine a computer that can learn, remember, and make complex decisions like a human brain, but with much more speed and efficiency.
Now imagine that this computer is powered by human brain cells, grown in a lab and assembled into tiny clusters called organoids. This is not science fiction, but a possible reality in the near future.
Organoid Intelligence (OI)
Researchers from Johns Hopkins University and Cortical Labs have proposed a new field of study called “organoid intelligence” or OI, which aims to create biocomputers based on human brain organoids.
These biocomputers could surpass today’s electronic computers for certain applications while using a small fraction of the electricity required by today’s computers and server farms.
Brain organoids are not mini brains, but they share key aspects of brain function and structure. They are derived from stem cells that can be reprogrammed into neurons and other brain cells.
They can form connections and networks, and exhibit basic forms of learning and memory. They can also be manipulated and stimulated by external signals, such as electrical impulses or light.
The researchers have already demonstrated that biocomputers based on human brain cells are possible. A recent paper in Neuron showed that a flat culture of brain cells could learn to play the video game Pong. The next step is to scale up the number of brain cells from around 50,000 to 10 million, which would be about the number of neurons in a tortoise brain.
Applications of Biocomputing
Biocomputers could be used to improve natural language processing (NLP) and language translation. According to computer scientist David Haussler, “The complexity of language and the richness of its meaning suggest that biocomputers might offer a superior way to process text, generate translations, or even interpret the subtle nuances of voice commands.”
Biocomputers could also be used for image and pattern recognition, which are computationally intensive tasks. As stated by biologist Michael Levin, “Biocomputers can perform these kinds of calculations at blazing speeds while consuming very little energy. They could lead to advances in facial recognition, cancer diagnosis, and drug discovery.”
Biocomputers could be used for anomaly detection, such as identifying fraudulent transactions or detecting network intrusions. According to computational neuroscientist Michael Bronstein, “The brain is very good at detecting deviations from the norm. By using biocomputers, we could create more efficient and accurate systems for detecting anomalies in large data sets.”
Biocomputers could be used to improve robotics and autonomous systems. According to neuroscientist Miyoung Chun, “Biocomputers could help create robots that can learn and adapt to their environment, like humans do. This could lead to more advanced and versatile robotics for manufacturing, space exploration, and even home care.”
Biocomputers could be used for personalized medicine, such as predicting a patient’s response to a particular treatment. As stated by physicist and neuroscientist Edward Boyden, “Biocomputers could simulate the behavior of individual cells and tissues, which could help doctors predict how a particular patient will respond to a drug or treatment. This could lead to more effective and personalized medicine.”
In 2019, a team of researchers from the University of California, San Diego, and the Salk Institute for Biological Studies reported that they had successfully created a “biological computer” using human stem cells. The team used induced pluripotent stem cells (iPSCs) to create clusters of brain cells called organoids, which were then integrated with an electronic circuit. The resulting device was able to perform a simple computational task, demonstrating that biocomputers based on brain cells are possible.
In another study published in the journal Neuron in 2020, researchers from the University of Pennsylvania and Carnegie Mellon University reported that they had created a biocomputer that could play the classic video game Pong. The biocomputer consisted of a flat culture of brain cells, which were trained to play the game using a reinforcement learning algorithm. The researchers found that the biocomputer was able to learn the game and improve its performance over time.
Recent Advances in Biocomputing
More recently, in 2021, researchers from Johns Hopkins University and Cortical Labs reported in the journal Neuron that they had created a biocomputer that could perform a simple optimization task. The biocomputer consisted of a network of brain organoids, which were connected to an electronic circuit and trained to find the shortest path between two points in a maze. The biocomputer was able to perform this task with a high degree of accuracy, demonstrating the potential of brain organoids for complex computation.
- Energy efficiency: One of the main advantages of biocomputers is their energy efficiency. While electronic computers require a significant amount of electricity to operate, biocomputers require only a small fraction of that energy. This is because brain cells are inherently efficient at processing information, and can perform complex computations using very little energy.
- Speed and parallel processing: Biocomputers could potentially process information much faster than electronic computers. This is because the neurons in the brain are able to perform calculations in parallel, rather than sequentially, as electronic computers do. This means that biocomputers could potentially perform many calculations simultaneously, leading to faster processing times and more efficient computations.
- Adaptability and learning: Biocomputers could also be more adaptable and capable of learning than electronic computers. This is because brain cells are capable of forming new connections and networks, and can learn and adapt based on their experiences. This could make biocomputers better suited for certain types of tasks, such as natural language processing or pattern recognition, that require a high degree of adaptability and learning.
- Novel computing paradigms: Biocomputing could also lead to the development of novel computing paradigms that are not possible with electronic computers. For example, biocomputers could be used to simulate complex biological systems, or to perform computations that are difficult or impossible with electronic computers. This could lead to breakthroughs in fields such as bioengineering, biophysics, and neuroscience.
Biocomputing is not without challenges and ethical issues.
The researchers acknowledge that there are many technical hurdles to overcome, such as how to interface with the brain organoids, how to monitor their activity and behavior, how to ensure their stability and reliability, and how to prevent them from degenerating or dying.
They also stress that biocomputing should be done with respect for human dignity and rights, and that brain organoids should not be considered as conscious or sentient entities.
Conclusion
Biocomputing is an exciting and promising frontier of science and technology. By harnessing the power of human brain cells, we could create a new kind of computer that could revolutionize our world.
