Synthetic Biological Intelligence: Researchers are exploring the creation of synthetic biological intelligence (SBI) by growing brain cells in a lab and integrating them into electronic circuitry to harness their unique properties for creating intelligent devices, using sustainable and ethical methods
Researchers are exploring the possibility of creating synthetic biological intelligence (SBI) by introducing biology to technology, rather than the reverse. This approach, known as synthetic biological intelligence, involves growing brain cells in a lab and integrating them into electronic circuitry. The goal is to leverage the fundamental building blocks of brains to create intelligent devices. The process of creating SBI is ethical and sustainable, as it does not require harvesting brain cells from animals. Researchers are using induced pluripotent stem cells, which can be generated from any adult donor's blood, tissue, or skin cells, to create brain cells. These cells are then integrated into devices called multi-electrode arrays, which allow for the recording and stimulation of electrical pulses in the brain cells. The ultimate goal is to harness the unique properties of brain cells to create intelligent devices, rather than trying to duplicate them in hardware.
Embodied networks: Embodied networks allow neurons to interact with a virtual world and receive feedback, enabling them to interpret signals and acquire real-world knowledge more effectively than traditional circuits, and they have the potential to learn rapidly and efficiently.
Neurons have the ability to spontaneously organize and communicate with each other when provided with information, leading to dramatic reorganization. This interaction between neurons and the information they receive is what forms the basis of embodied networks. Unlike traditional approaches that focus on adding circuits to neurons or vice versa, embodied networks aim to create a closed loop system where neurons interact with a virtual world and receive feedback, creating a barrier between their activity and the external world. This embodiment allows neurons to interpret signals and acquire real-world knowledge more effectively than traditional circuits. The potential of embodied networks lies in their ability to learn rapidly and efficiently, making them a promising area for future research and applications.
Neuron learning and reorganization: Researchers observe rapid neuron learning and upregulation, called heavy plasticity, within minutes in response to stimuli, which could lead to advancements in AGI
Researchers are exploring how neurons learn and reorganize in response to stimuli in real-time, using the example of neurons playing a simple poem. They've observed learning happening within minutes, specifically a process called heavy plasticity. This rapid upregulation of neurons is just one part of the complexity of these systems, and further research is needed to understand the full extent of these interactions. The potential implications of this research could lead to advancements in artificial generalized intelligence, as biological systems have the ability to make associations and learn from their environment in a way that current computers cannot. However, it's important to note that this research is still in its early stages and raises ethical considerations. The ultimate goal is to understand the fundamental basis of intelligence and how to replicate it in a controlled and ethical manner.
Synthetic Biological Intelligence: Researchers developed a synthetic biological intelligence system that learns to minimize uncertainty, rapidly changes behavior, requires less data and power, and is not yet scalable for large-scale problems, contrasting biological and silicon intelligence.
A team of researchers, working with neuroscientist Professor Carl Friston, have developed a synthetic biological intelligence system that learns to minimize uncertainty in its environment based on the Free Energy Principle. This system, when tested, showed rapid behavior changes at various levels. Unlike machine learning algorithms, synthetic biological intelligence requires less data and power to reach similar learning milestones. The team disconnected the input and output information to ensure the system was learning internally. This intelligence, though energy-efficient, is not yet scalable for large-scale problems. The debate between biological and silicon intelligence raises ethical concerns, but the fundamental differences lie in the natural, dynamic, and critical processes of biological systems, contrasting the rigidity of silicon computing.
Neuroethics and consciousness: As neurotechnology advances, ethical considerations related to consciousness and its relation to intelligence become increasingly important. Ethical concerns can be categorized into donor ethics, applications, and consciousness itself, requiring ongoing debate and exploration involving ethicists and neuroscientists.
As we advance in neurotechnology, ethical considerations become increasingly important, particularly regarding consciousness and its relation to intelligence. While consciousness and intelligence are not inherently tied, the potential for creating consciousness in artificial systems raises ethical questions. Researchers are working with bioethicists to understand the moral relevance of consciousness and the biological basis for morally relevant states. The ethical concerns can be categorized into three areas: donor ethics, applications, and consciousness itself. While some ethical issues, like donor ethics, are being addressed through advancements in stem cell therapy, others, like consciousness and its potential emergence in artificial systems, require ongoing debate and exploration. It's crucial to involve ethicists and neuroscientists in these discussions to ensure ethical progress in this field. The potential implications of understanding consciousness extend beyond the lab, potentially changing how we interact with the natural world.
Synthetic Biological Intelligence: Synthetic Biological Intelligence holds immense potential for various fields, but requires a multidisciplinary approach and ethical considerations to fully realize its capabilities
As we explore the complexities of synthetic biological intelligence, we must approach it with humility and caution. While we don't have all the answers, we can work together to identify the best ways to test and understand this emerging field. The future of computing may involve a hybrid of synthetic and biological intelligence, each solving problems in unique ways. However, it's important to consider the potential implications and limitations of biological computation. This technology holds immense potential for various fields, including healthcare and data processing, but it requires a multidisciplinary approach to fully realize its capabilities. Ultimately, we must continue to ask questions and push the boundaries of what's possible, while remaining aware of the potential challenges and ethical considerations.
Game development and neuroscience: Game development innovation led to neuro-computational models, aiding neuroscience research, drug development, and understanding brain functions.
The early developers of computer games faced challenges using off-the-shelf hardware and decided to build their own platforms to make game development more efficient. This innovation led to rapid iteration and advancements in understanding neuro-computational questions, potentially contributing to the field of neuroscience and brain research. The use of neuro-computational models in game development can help us understand the brain's electrochemical responses to drugs and diseases, providing valuable insights for developing effective treatments. The importance of understanding the balance between order and chaos in information processing is crucial for various functions, including memory, intelligence, and emergent properties in complex systems. Neurons in different parts of the brain have distinct functions and behaviors, and studying their activity in circuits can reveal valuable information about their roles in specific brain functions.

Neuroscientist Brett Kagan is leading the charge in understanding the complexities of the brain through synthetic biology and bioengineering, with the potential to revolutionize fields from drug discovery to computation. Kagan emphasizes that this work is driven by the human curiosity to understand the unknown and optimize, rather than any fear of artificial intelligence becoming an overlord. The founder of his company shares this vision, aiming to create a legacy and change the way things are done, rather than just making money. Kagan's work, which includes studying hippocampal cells and learning from nature's communication methods like bees, holds immense promise for the future. Despite the challenges of funding and time, the excitement and potential for discovery keep scientists like Kagan pushing forward.
