Recent advancements in neuroscience and brain-inspired artificial intelligence have brought new possibilities in the study of intelligence. Driven by this, Tianzi Jiang and his research team at the Institute of Automation of the Chinese Academy of Sciences have developed a groundbreaking platform called the Digital Twin Brain. This innovative platform aims to bridge the gap between biological and artificial intelligence, providing valuable insights into both fields. In their published research in Intelligent Computing, the team outlines the key components and properties of the Digital Twin Brain, highlighting its potential to propel the development of artificial general intelligence and revolutionize precision mental health care.
The common thread between biological and artificial intelligence lies in their network structure. By constructing a digital model, or “twin,” of the brain using artificial networks, researchers can leverage knowledge about biological intelligence to enhance the model. The Digital Twin Brain offers a unique opportunity to explore the working mechanisms of the human brain through simulation and modulation. This allows researchers to understand how the brain functions in different states for various cognitive tasks, including resting and disorders, and even develop methods to modulate its activity away from undesirable states.
The Digital Twin Brain integrates three core elements to create a powerful and dynamic platform. Firstly, brain atlases act as the structural scaffolds and biological constraints, providing the necessary groundwork for building its digital counterpart. These atlases, which encompass various scales, species, and modalities, enable researchers to explore the fundamental principles of brain organization and the interactions between different regions. Secondly, multi-level neural models trained on biological data enable realistic simulations of brain functions. As the dynamic brain atlas evolves, these neural models continually improve, enhancing the fidelity of the digital twin. Lastly, a range of applications is employed to evaluate and update the current state of the digital twin, fostering a closed-loop system. These applications encompass disease biomarker discovery, drug testing, and other practical scenarios, providing valuable feedback to enhance the brain atlas.
To construct an accurate digital twin, sophisticated brain atlases are crucial. These atlases must account for intricate brain structures, complex dynamics, and even species diversity. The Brainnetome Atlas, developed by the Institute of Automation of the Chinese Academy of Sciences, is one such atlas that plays a significant role in developing the Digital Twin Brain. This atlas, encompassing 246 brain sub-regions, provides an extensive mapping of the structure and connectivity of the human brain. In parallel, an open-source, efficient, flexible, and user-friendly brain atlas-constrained platform is required to support multiscale and multimodal modeling. Overcoming these challenges will enable researchers to effectively integrate biological knowledge into the digital twin and design better models for simulations.
The Digital Twin Brain represents a remarkable convergence of neuroscience and artificial intelligence. Through the integration of intricate brain atlases, dynamic neural models, and a plethora of applications, this platform has the potential to revolutionize our understanding of both biological and artificial intelligence. Moreover, with wide collaboration among scientists worldwide, the Digital Twin Brain has the capacity to advance artificial general intelligence and transform precision mental health care. By unlocking transformative breakthroughs, this platform opens the doors to a deeper understanding of the human mind, the development of intelligent technologies, and the discovery of therapeutics for brain disorders.
The Digital Twin Brain stands as an innovative and promising solution in the field of intelligence research. Its ability to bridge the gap between biological and artificial intelligence offers unprecedented opportunities for exploration and advancement. With further developments and collaborations, this platform holds immense potential for shaping the future of intelligence and revolutionizing our approach to mental health care.
