BACKGROUND OF THE INVENTION
There is considerably interest (reflected by a European initiative and a NATO program) on the construction of human digital twins. The field of artificial intelligence (AI) is highly relevant to constructing a digital twin, particularly with its novel neural network architectures and machine learning. However, achieving a detailed and accurate emulation of the human brain remains a complex challenge. A digital twin that only operates as an LLM would not have the full complexity of human neuropsychological emulation required for an adequate emulation of the human mind, which is according to certain neuropsychological theories identical to the human brain (Tucker & Luu, Cognition & Neural Development, Oxford Press, 2012).
Existing systems lack the capacity to comprehensively model the intricacies of human cerebral architecture. Recent advancements in neuromorphic computing and the theory of active inference suggest that it is possible to create a computational emulation of a human brain, capturing the essential features that define individual identity and subjective experience (Feasibility of a Personal Neuromorphic Emulation doi: 10.20944/preprints202407.1147). An essential component is the achievement of Bayesian super-resolution that the PNE allows through its capacity to predict the neural, and therefore electrical, activity of the human brain in very high resolution. Necessary computational capacities are now emerging in neuromorphic quantum computing, presenting an attractive preferred embodiment for the construction of the PNE. The present invention draws on these capacities to create a Neuromorphic Emulation Constructor AI (NECA) designed to construct precise computational models of an individual human brain by leveraging extensive scientific literature, data, and continuous very-high-definition electroencephalography (vhdEEG) monitoring.
SUMMARY OF THE INVENTION
The present invention relates to a Neuromorphic Emulation Constructor AI (NECA) capable of constructing an exact computational emulation of a person's brain. The NECA is designed to access scientific literature through search engines like Google Scholar, analyze and process scientific articles, and provide guidance for the construction of a multi-level model of human cerebral architecture. Additionally, the system incorporates 24/7 vert high-definition electroencephalography (vhdEEG) monitoring with source localization (augmented by the parallel invention of synergistic Bayesian super-resolution for the Bayesian Adaptive Neural Interface) to enhance the accuracy and fidelity of the Personal Neuromorphic Emulation (PNE). Finally, a companion invention, the Neuromorphic Artificial Neural Network Assistant (NANNA) is a virtual personal assistant that not only completes routine tasks for the person in daily life, but also collects a detailed record of the person's experiences and behavior to allow the PNE to be trained (with the NECA's help) to achieve a precise emulation of the person's experience and behavior as well as her neural activity as captured.
DESCRIPTION OF THE DRAWING
FIG. 1 illustrates the overall design and primary information processing flow for the NECA.
10 The NECA creates the PNE (60) on the basis of scientific evidence on human neural architecture.
20 An interface to Google Scholar uses keywords to access the scientific literature for evidence on the anatomy and function of the human brain, informed by the animal neuroscience literature as well.
30 The relevance of each scientific paper is judged by the value estimator AI LLM on the basis of the NECA's progress in constructing the PNE (and what information is currently relevant).
40 The new scientific evidence is organized in relation to various levels of information communication in the brain, specifically in relation to the levels of network organization (columnar, local regional, long distance networks).
50 These levels of information (10 through 40) are organized in relation to an ontology of the human brain's anatomy and function.
60 The output of the NECA is the PNE, the emulation of an individual's brain/mind.
70 The PNE is trained in relation to its ability to predict both the behavior and the electrophysiology (hdEEG) of the person. In addition, hdtES allows experimentation with two-way interface with the electrical fields of the person's brain.
DETAILED DESCRIPTION OF THE INVENTION
Foundational Principles
The invention leverages several foundational principles and recent advancements to achieve its objectives:
- Distributed Representation and Neurodevelopmental Identity:
- The memory and cognitive functions in both biological brains and artificial neural networks are implemented through distributed representations of connection weights among neurons. These representations are dynamic, continuously evolving through learning and experience.
- Informatic Basis of Organisms:
- The processes of living organisms, including their cognitive functions, can be described in terms of information theory. This includes the minimization of free energy and maintaining a non-equilibrium steady state (NESS), which are essential for self-organizing systems.
- High-Resolution Neuroinformatic Data:
- By employing hdEEG and source localization techniques, the system can gather high-resolution data on an individual's brain activity, capturing the intricate details of their neural connections and functional states.
- Active Inference and Self-Regulation:
- The NECA uses active inference to model and predict the brain's responses, continuously updating the PNE based on real-time data. This allows the emulation to adapt and self-regulate, closely mimicking the individual's cognitive processes.
- Neuroinformatic Replication:
- The combined capabilities of PNE and NECA enable the creation of a durable neuroinformatic replication of an individual's brain, preserving their subjective self and cognitive functions in a computational form.
- The Subjective Turing Test: If the PNE is trained to precisely emulate the person's neural activity, experience, and behavior, then the interface of the person's brain with the PNE (through two-way communication with the hdEEG/tES interface) allows the person to subjectively evaluate the quality of the emulation.
Feasibility Analysis
The paper by Tucker and Luu (2024; doi: 10.20944/preprints202407.1147.v1) supports the feasibility of this approach, highlighting the theoretical and practical advancements that make it possible to construct an accurate PNE. The principles of active inference, neurodevelopmental identity, and the informatic basis of organisms provide a robust framework for achieving a high-fidelity emulation of the human brain.

- Long-Term Monitoring: Continuous monitoring over months or years allows for detailed tracking of brain activity and enhances the fidelity of the PNE.
- Extension to Bayesian Super-Resolution: The related invention of Bayesian super-resolution by Tucker, Luu, and Shusterman draws on the predictive model of an initial PNE to predict the electrical fields of small patches of cortical columns, which can be trained with the native resolution of hdEEG to achieve very high definition EEG (vhdEEG) that is then available for further training with the NECA system.
Personal Neuromorphic Emulation (PNE)
- Individualized Modeling: The NECA uses personal brain data (e.g., MRI scans, neurophysiological recordings, hdEEG data) to tailor the emulation to a specific individual.
- Validation and Testing: The PNE undergoes rigorous validation and testing to ensure its accuracy and fidelity in replicating the individual's brain functions. The NECA provides the plasticity control over the PNE to adapt its architecture to achieve a precise emulation/prediction of the person's regional neuroelectric fields in order to train and validate the PNE's effective emulation of the person's brain.
