This study explores the feasibility of developing a dynamic cognovisor capable of recognizing cognitive states and transitions using fMRI data. Data were collected from 31 participants performing spatial and verbal tasks during fMRI scanning and were preprocessed using a nine-step algorithm for artifact removal and denoising. Three types of classification problems were examined, with machine learning methods and dimensionality reduction techniques applied to classify activity states. The best-performing models were identified for each classification problem, providing insights into their applicability. Notably, binary classification of resting versus active states achieved good quality with relatively simple methods. A key finding underscores the importance of accounting for temporal history of the signal prior to the prediction moment to improve model performance.

At present, implementation of learning mechanisms in spiking neural networks (SNN) cannot be considered as a solved scientific problem despite plenty of SNN learning algorithms proposed. It is also true for SNN implementation of reinforcement learning (RL), while RL is especially important for SNNs because of its close relationship to the domains most promising from the viewpoint of SNN application such as robotics. In the present paper, an SNN structure is described which, seemingly, can be used in wide range of RL tasks. The distinctive feature of our approach is usage of only the spike forms of all signals involved — sensory input streams, output signals sent to actuators and reward/punishment signals. Besides that, selection of the neuron/plasticity models was determined by the requirement that they should be easily implemented on modern neurochips. The SNN structure considered in the paper includes spiking neurons described by a generalization of the LIFAT (leaky integrate-and-fire neuron with adaptive threshold) model and a simple spike timing dependent synaptic plasticity model (a generalization of dopamine-modulated plasticity). In this study, we use the model-free approach to RL but it is based on very general assumptions about RL task characteristics and has no visible limitations on its applicability (inside the class of model-free RL tasks). To test our SNN, we apply it to a simple but non-trivial task of training the network to keep a chaotically moving light spot in the view field of an emulated Dynamic Vision Sensor (DVS) camera. Successful solution of this RL problem can be considered as an evidence in favor of efficiency of our approach.

Prenatal maternal stress (PNMS) has significant implications for infant temperament, primarily through alterations in the hypothalamic–pituitary–adrenal (HPA) axis and epigenetic mechanisms. This study explores the effects of PNMS on infant stress reactivity using a fifth-order adaptive dynamical system model. The model integrates genetic, epigenetic, and environmental factors, focusing on the downregulation of 11β-HSD-2, an enzyme responsible for converting active cortisol to its inactive form, and its subsequent influence on fetal cortisol exposure. The article also employs network-oriented modeling to represent epigenetic changes and their impact on infant temperament development, emphasizing the HPA axis’ role in stress regulation. Simulation experiments compare scenarios with PNMS, illustrating the long-term developmental consequences on temperament. This research highlights the importance of maternal well-being during pregnancy in shaping infant stress responses and provides insights into the developmental origins of health and disease.

Behavioral decision-making in unknown environments of mobile robots is a crucial research topic in robotics. Inspired by the working mechanism of different brain regions in mammals, this paper designed a new hybrid model integrating the functions of cerebellum and basal ganglia by simulating the memory replay of hippocampus, so as to realize the autonomous behavioral decision-making of robot in unknown environments. A reinforcement learning module based on Actor-Critic framework and a developmental network module are used to simulate the functions of the basal ganglia and cerebellum, respectively. Considering the different functions of D1 and D2 dopamine receptors in basal ganglia, an Actor network module with separate learning of positive and negative rewards is designed for the basal ganglia to realize efficient exploration of the environments by the agent. According to the characteristics of biological memory, a physiological memory priority index is designed for hippocampus memory replay, which improves the offline learning efficiency of cerebellum. The integrated model enables dynamic switching between decisions made by cerebellum and basal ganglia based on the agent’s cognitive level with respect to the environment. Finally, the effectiveness of the proposed model is verified through experiments on agent navigation in both simulation and real environments, as well as through performance comparison experiments with other learning algorithms.
移动机器人在未知环境中的行为决策是机器人学的一个重要研究课题。受哺乳动物不同脑区工作机制的启发，本文通过模拟海马的记忆重放，设计了一种整合小脑和基底节功能的新型混合模型，以实现机器人在未知环境中的自主行为决策。基于 Actor-Critic 框架的强化学习模块和发育网络模块分别用于模拟基底节和小脑的功能。考虑到基底节中多巴胺受体 D1 和 D2 的不同功能，为基底节设计了分别学习正负奖励的 Actor 网络模块，以实现机器人对环境的高效探索。根据生物记忆的特点，为海马记忆重放设计了生理记忆优先级指标，提高了小脑的离线学习效率。综合模型可根据代理对环境的认知水平，实现小脑和基底神经节决策的动态切换。最后，通过在模拟和真实环境中进行的代理导航实验，以及与其他学习算法的性能对比实验，验证了所提模型的有效性。

We examine preliminary results from the first automated system to detect the 188 cognitive biases included in the 2016 Cognitive Bias Codex, as applied to both human and AI-generated text, and compared to a human baseline of performance. The human baseline was constructed from the collective intelligence of a small but diverse group of volunteers independently submitting their detected cognitive biases for each sample in the task used for the first phase. This baseline was used as an approximation of the ground truth on this task, for lack of any prior established and relevant benchmark. Results showed the system’s performance to be above that of the average human, but below that of the top-performing human and the collective, with greater performance on a subset of 18 out of the 24 categories in the codex. This version of the system was also applied to analyzing responses to 150 open-ended questions put to each of the top 5 performing closed and open-source Large Language Models, as of the time of testing. Results from this second phase showed measurably higher rates of cognitive bias detection across roughly half of all categories than those observed when analyzing human-generated text. The level of model contamination was also considered for two types of contamination observed, where the models gave canned responses. Levels of cognitive bias detected in each model were compared both to one another and to data from the first phase.

The discovery of various cognitive biases and social illusions indicates that people routinely have misbeliefs. Focusing on the illusion of control (IOC), this article argues that when time and cognitive resources are limited, and information is imperfect, misbeliefs can be generated naturally in a normal belief formation system, and these misbeliefs might help people adapt better to the environment. In this study, we present a computational model—the informativeness-weighting model (IWM)—describing how beliefs are revised by observed evidence. To be precise, IOC is the result of distinct types of evidence being endowed with different weights according to its informativeness in a belief revision process. To evaluate the model, we also designed two behavioral experiments to compare people’s sense of control with that predicted by the model. In both experiments, our model outperformed two alternative models in predicting and explaining the misestimation of people’s perceived control. Thus, we suggest that our model reflects an adaptive strategy for information processing, which helps to explain why misbeliefs, like IOC, are prevalent in human cognition.

Many complex decision-making scenarios encountered in the real-world, including energy systems and infrastructure planning, can be formulated as constrained optimization problems. Solutions for these problems are often obtained using white-box solvers based on linear program representations. Even though these algorithms are well understood and the optimality of the solution is guaranteed, explanations for the solutions are still necessary to build trust and ensure the implementation of policies. Solution algorithms represent the problem in a high-dimensional abstract space, which does not translate well to intuitive explanations for lay people. Here, we report three studies in which we pose constrained optimization problems in the form of a computer game to participants. In the game, called Furniture Factory, participants manage a company that produces furniture. In two qualitative studies, we first elicit representations and heuristics with concurrent explanations and validate their use in post-hoc explanations. We analyze the complexity of the explanations given by participants to gain a deeper understanding of how complex cognitively adequate explanations should be. Based on insights from the analysis of the two qualitative studies, we formalize strategies that in combination can act as descriptors for participants’ behavior and optimal solutions. We match the strategies to decisions in a large behavioral dataset ( participants) gathered in a third study, and compare the complexity of strategy combinations to the complexity featured in participants’ explanations. Based on the analyses from these three studies, we discuss how these insights can inform the automatic generation of cognitively adequate explanations in future AI systems.

The development of brain-morphic software holds significant promise for creating artificial general intelligence that exhibits high affinity and interpretability for humans and also offers substantial benefits for medical applications. To facilitate this, creating Brain Reference Architecture (BRA) data, serving as a design specification for brain-morphic software is imperative. BRA-driven development, which utilizes Brain Information Flow (BIF) diagrams based on mesoscale brain anatomy and Hypothetical Component Diagrams (HCD) for corresponding computational functionalities, has been proposed to address this need. This methodology formalizes identifying possible functional structures by leveraging existing, albeit insufficient, neuroscientific knowledge. However, applying this methodology across the entire brain, thereby creating a Whole Brain Reference Architecture (WBRA), represents a significant research and development challenge due to its scale and complexity. Technology roadmaps have been introduced as a strategic tool to guide discussion, management, and distribution of resources within such expansive research and development activities. These roadmaps proposed a manual, anatomically based approach to incrementally construct BIF and HCD, thereby systematically expanding brain organ coverage toward achieving a complete WBRA. Large Language Model (LLM) technologies have introduced a paradigm shift, substantially automating the BRA-driven development process. This is largely due to the BRA data being structured around the brain’s anatomy and described in natural language, which aligns well with the capabilities of LLMs for supporting and automating the construction and verification processes. In this paper, we propose a novel technology roadmap to largely automate the creation of WBRA, leveraging neuroscientific insights. This roadmap includes 12 activities for automating BIF construction, notably extracting anatomical structures from scholarly articles. Furthermore, it details 11 activities aimed at enhancing the integration of Hypothetical Component Diagrams (HCD) into the WBRA, focusing on automating checks for functional consistency. This roadmap aims to establish a cost-effective and efficient design process for WBRA, ensuring the availability of brain-morphic software design specifications that are continually validated against the latest neuroscientific knowledge.
脑形态软件的开发为创造人工通用智能带来了巨大的希望，这种人工通用智能与人类具有高度的亲和力和可解释性，同时也为医疗应用带来了巨大的好处。为此，必须创建脑参考架构（BRA）数据，作为脑形态软件的设计规范。为了满足这一需求，我们提出了基于中尺度大脑解剖学的脑信息流图（Brain Information Flow，BIF）和相应计算功能的假设组件图（Hypothetical Component Diagrams，HCD）的脑参考架构驱动开发方法。这种方法通过利用现有的神经科学知识（尽管还不够充分），将识别可能的功能结构正规化。然而，将这种方法应用于整个大脑，从而创建全脑参考架构（WBRA），由于其规模和复杂性，是一项重大的研发挑战。技术路线图已被作为一种战略工具引入，用于指导此类大规模研发活动中的讨论、管理和资源分配。这些路线图提出了一种基于解剖学的手动方法，以逐步构建 BIF 和 HCD，从而系统地扩大大脑器官的覆盖范围，实现完整的 WBRA。大型语言模型（LLM）技术带来了范式的转变，使 BRA 驱动的开发过程大大自动化。这主要是由于 BRA 数据是围绕大脑解剖结构并用自然语言描述的，这与 LLM 在支持和自动化构建和验证过程方面的能力非常吻合。在本文中，我们提出了一个新颖的技术路线图，利用神经科学的洞察力，在很大程度上实现 WBRA 创建的自动化。该路线图包括 12 项自动构建 BIF 的活动，特别是从学术文章中提取解剖结构。此外，它还详细介绍了 11 项旨在加强将假想成分图 (HCD) 整合到 WBRA 中的活动，重点是自动检查功能一致性。该路线图旨在为 WBRA 建立一个经济高效的设计流程，确保提供根据最新神经科学知识不断验证的脑形态软件设计规范。

The idea of reproducing personality by means of digital (neural network) technologies (“digital immortality”), together with the concept of Digital Twin (DT), still attracts great attention. Recent advances in the DT industry permit to expect the production of perfect “mirror” DT in the near future. We argue that the “immortality in the memory of other people” could be approached quite closely due to creating an analogue of personal DT by simulating the personality. For this purpose, it is necessary to compose the “constructive portrait” of a chosen person (by extracting the key features and traits of personality) and try to reproduce it by means of a chosen model. We are developing an original model Natural Constructive Cognitive Architecture (NCCA) that inherently provides the interpretation of logical and intuitive thinking, subconscious, etc. This model should be adjusted to specific set of knowledge inherent in a particular person (books, films, photographs, etc.), with an emphasis on personal lexicons (verbal, emotion, behavioral). NCCA contains a large set of free model parameters, which enables us to reproduce a wide range of personality features, from thinking style to temperament. It is shown that popular Generative Pre-trained Transformers (GPTs) have much in common with NCCA and could be adapted and used as an analog of DT of a specific person. We argue that the proposed program would provide the possibility to create an analog of DT, which could give an impression (at least, an illusion) of communication with the desired specific person.
