Recent advancements in neuroscience and brain-inspired artificial intelligence have opened up unprecedented possibilities in understanding intelligence. A breakthrough study led by Tianzi Jiang at the Institute of Automation of the Chinese Academy of Sciences introduces the Digital Twin Brain, an innovative platform that has the potential to bridge the gap between biological and artificial intelligence. This cutting-edge research, published in Intelligent Computing, outlines the key components and properties of this platform, offering new insights into the field.
One of the fundamental characteristics shared by both biological and artificial intelligence is their network structure. The human brain, being a complex biological network, can be emulated through the construction of a digital twin using artificial networks. This approach allows researchers to transfer knowledge about biological intelligence and utilize it in the model. The ultimate objective is to drive the development of artificial general intelligence and revolutionize precision mental health care, necessitating collaborative efforts from interdisciplinary scientists across the globe.
By leveraging the capabilities of the Digital Twin Brain, researchers can delve into the mechanisms underlying the human brain’s functions. Simulating and modulating the brain in different states for various cognitive tasks allows scientists to understand how the brain operates optimally during rest and how it malfunctions in disorders. Moreover, this groundbreaking platform opens doors to developing methods that shift the brain away from undesirable states by modulating its activity. Although the Digital Twin Brain may initially sound like a concept from science fiction, it stands firmly grounded in biological principles and offers immense potential for advancements.
The Digital Twin Brain integrates three core elements: brain atlases, multi-level neural models, and a spectrum of applications. Brain atlases serve as the structural framework and biological constraints for the platform. These highly nuanced atlases, encompassing different scales, modalities, and species, facilitate a comprehensive exploration of brain organization and connectivity. However, they also pose technical challenges, as neural models must be based on them in order to maintain “biological plausibility.”
To enhance the accuracy of function simulations, the Digital Twin Brain incorporates multi-level neural models trained on biological data. By continuously updating and validating these models across an expanding range of practical applications, such as disease biomarker discovery and drug testing, the platform ensures a closed feedback loop. This loop enables the refinement and enhancement of the brain atlas, further improving neural models and their function simulations.
The Brainnetome Atlas, announced by researchers at the Institute of Automation of the Chinese Academy of Sciences in 2016, emerges as a critical component for the development of the Digital Twin Brain. This macroscale atlas comprises 246 brain sub-regions and continually evolves to provide an extensive and detailed mapping of the human brain’s structure and connectivity. Furthermore, the authors suggest the need for an open-source, efficient, flexible, and user-friendly brain atlas-constrained platform powerful enough to support multiscale and multimodal modeling.
While the Digital Twin Brain holds incredible potential, there are still numerous questions that need to be addressed. Effective integration of biological knowledge into the digital twin, designing better models for simulations, and seamless integration into practical scenarios are just a few challenges that lie ahead. By collectively tackling these challenges, the Digital Twin Brain has the capability to revolutionize our understanding of both biological and artificial intelligence.
The Digital Twin Brain represents a groundbreaking convergence between neuroscience and artificial intelligence. By incorporating intricate brain atlases, dynamic neural models, and a diverse range of applications, this platform stands on the cusp of a revolution in our understanding of the human mind and the development of intelligent technologies. It holds the potential to advance artificial general intelligence and pave the way for transformative breakthroughs in precision mental health care and the discovery of therapeutics for brain disorders. Through the collaborative efforts of scientists worldwide, the Digital Twin Brain unlocks a promising future, where the boundaries of intelligence are pushed to new horizons.
