Understanding the influence of digital technology on human cognitive functions: A narrative review

Application of Artificial Intelligence in the Securities Market

Artificial Intelligence (AI) involves creating machines that replicate human cognitive functions, enabling them to think and act similarly to people. In the context of stock trading, AI refers to the use of technology designed to buy and sell shares with increased precision and efficiency compared to human capabilities. AI-driven systems are currently employed to predict stock market trends and analyze trading patterns among investors and brokers. Prominent financial institutions on Wall Street, such as Goldman Sachs and Morgan Stanley, are increasingly adopting specialized AI solutions, including data mining, natural language processing, and self-learning algorithms. These tools operate with greater speed than everyday applications. Additionally, AI aids wealth management firms in continuously monitoring market movements and adjusting portfolios to achieve target profits. While AI can significantly reduce workload and provide real-time recommendations, it does not entirely eliminate the need for human oversight. Keywords: artificial intelligence, securities, trading, forecasting.

The Co-Piloting Model for Using Artificial Intelligence Systems in Medicine: Implementing the Constrained-Disorder-Principle-Based Second-Generation System

The development of artificial intelligence (AI) and machine learning (ML)-based systems in medicine is growing, and these systems are being used for disease diagnosis, drug development, and treatment personalization. Some of these systems are designed to perform activities that demand human cognitive function. However, use of these systems in routine care by patients and caregivers lags behind expectations. This paper reviews several challenges that healthcare systems face and the obstacles of integrating digital systems into routine care. This paper focuses on integrating digital systems with human physicians. It describes second-generation AI systems designed to move closer to biology and reduce complexity, augmenting but not replacing physicians to improve patient outcomes. The constrained disorder principle (CDP) defines complex biological systems by their degree of regulated variability. This paper describes the CDP-based second-generation AI platform, which is the basis for the Digital Pill that is humanizing AI by moving closer to human biology via using the inherent variability of biological systems for improving outcomes. This system augments physicians, assisting them in decision-making to improve patients’ responses and adherence but not replacing healthcare providers. It restores the efficacy of chronic drugs and improves adherence while generating data-driven therapeutic regimens. While AI can substitute for many medical activities, it is unlikely to replace human physicians. Human doctors will continue serving patients with capabilities augmented by AI. The described co-piloting model better reflects biological pathways and provides assistance to physicians for better care.

An overview of the relationship between inflammation and cognitive function in humans, molecular pathways and the impact of nutraceuticals

Inflammation has been associated with cognitive decline, whether in the peripheral or central nervous systems. The primary mechanism involves the response of microglia, an immune cell in the brain, which generates pro-inflammatory mediators such as cytokines, chemokines, and adhesion molecules. The excessive production of pro-inflammatory mediators may accelerate the damage to neurons, contributing to the development of neurodegenerative diseases such as Alzheimer’s disease, mild cognitive impairment, and vascular dementia, as well as a general decline in cognitive function. Various studies have supported the correlation between elevated pro-inflammatory mediators and a decline in cognitive function, particularly in aging and age-related neurodegenerative diseases. Moreover, this association has also been observed in other inflammatory-related conditions, including post-operative cognitive impairment, diabetes, stroke, obesity, and cancer. However, the interaction between inflammatory processes and cognitive function in humans remains unclear and varies according to different health conditions. Therefore, this review aims to consolidate and evaluate the available evidence from original studies as well as meta-analyses in order to provide a greater understanding of the inflammatory process in connection with cognitive function in humans. Furthermore, relevant biological cellular processes, putative inflammatory biomarkers, and the role of nutraceuticals on the interaction between cognitive performance and inflammatory status are outlined.

MAPbrain: a multi-omics atlas of the primate brain.

The brain is the central hub of the entire nervous system. Its development is a lifelong process guided by a genetic blueprint. Understanding how genes influence brain development is critical for deciphering the formation of human cognitive functions and the underlying mechanisms of neurological disorders. Recent advances in multi-omics techniques have now made it possible to explore these aspects comprehensively. However, integrating and analyzing extensive multi-omics data presents significant challenges. Here, we introduced MAPbrain (http://bigdata.ibp.ac.cn/mapBRAIN/), a multi-omics atlas of the primate brain. This repository integrates and normalizes both our own lab's published data and publicly available multi-omics data, encompassing 21 million brain cells from 38 key brain regions and 436 sub-regions across embryonic and adult stages, with 164 time points in humans and non-human primates. MAPbrain offers a unique, robust, and interactive platform that includes transcriptomics, epigenomics, and spatial transcriptomics data, facilitating a comprehensive exploration of brain development. The platform enables the exploration of cell type- and time point-specific markers, gene expression comparison between brain regions and species, joint analyses across transcriptome and epigenome, and navigation of cell types across species, brain regions, and development stages. Additionally, MAPbrain provides an online integration module for users to navigate and analyze their own data within the platform.

Challenging large language models’ “intelligence” with human tools: A neuropsychological investigation in Italian language on prefrontal functioning

The Artificial Intelligence (AI) research community has used ad-hoc benchmarks to measure the “intelligence” level of Large Language Models (LLMs). In humans, intelligence is closely linked to the functional integrity of the prefrontal lobes, which are essential for higher-order cognitive processes. Previous research has found that LLMs struggle with cognitive tasks that rely on these prefrontal functions, highlighting a significant challenge in replicating human-like intelligence. In December 2022, OpenAI released ChatGPT, a new chatbot based on the GPT-3.5 model that quickly gained popularity for its impressive ability to understand and respond to human instructions, suggesting a significant step towards intelligent behaviour in AI. Therefore, to rigorously investigate LLMs' level of “intelligence,” we evaluated the GPT-3.5 and GPT-4 versions through a neuropsychological assessment using tests in the Italian language routinely employed to assess prefrontal functioning in humans. The same tests were also administered to Claude2 and Llama2 to verify whether similar language models perform similarly in prefrontal tests. When using human performance as a reference, GPT-3.5 showed inhomogeneous results on prefrontal tests, with some tests well above average, others in the lower range, and others frankly impaired. Specifically, we have identified poor planning abilities and difficulty in recognising semantic absurdities and understanding others' intentions and mental states. Claude2 exhibited a similar pattern to GPT-3.5, while Llama2 performed poorly in almost all tests. These inconsistent profiles highlight how LLMs' emergent abilities do not yet mimic human cognitive functioning. The sole exception was GPT-4, which performed within the normative range for all the tasks except planning. Furthermore, we showed how standardised neuropsychological batteries developed to assess human cognitive functions may be suitable for challenging LLMs’ performance.

Scientific problems of ensuring technological sovereignty in the field of artificial intelligence technologies

The article discusses the scientific problems of ensuring technological sovereignty in the field of artificial intelligence technologies. One of the key scientific problems is computer modeling of human cognitive functions with finite resources, which provide the ability to process and analyze finite–dimensional and infinite-dimensional data along with finite-dimensional ones. A well–known solution to this problem is the A.N. Tikhonov regularization method, due to the high complexity and cost of implementation of which, less complex and expensive empirically constructed foreign INS are used to build AI solutions, but without guarantees of error-free results. The consequence of this is a rather low level of implementation of AI solutions in industry and in the field of information technology and a practical lack of data on the economic effect. It is proposed to consider the economic efficiency of domestic AI solutions as the main criterion for the need for their development.

Effects of natural reduced water on cognitive functions in older adults: A RCT study

Oxidative stress and diabetes increase the risk of cognitive decline and dementia. Natural reduced water contains active hydrogen (hydrogen radicals), eliminates reactive oxygen species, and has antidiabetic effects. However, whether natural reduced water affects human cognitive function is unknown. Therefore, we implemented a double-blind intervention experiment in which participants consumed 1 L of natural reduced water or tap water daily for 6 months. The participants were healthy older adults living in Japan. The intervention group showed significant improvements in cognitive functions of attention function (p < 0.01) and short-term memory (p < 0.05). These results indicate that the continuous intake of natural reduced water improves several cognitive functions.

What drives the corporate payoffs of using generative artificial intelligence?

Artificial Intelligence, a set of technologies that aim to replicate human cognitive functions, has seen remarkable improvements over the last decade. In particular, generative AI (GenAI), a subset of AI able to generate content tasks based on Large Language Models (LLM), has recently gained momentum. Based on an extensive analysis of generative AI use cases in large enterprises, we find that Gen AI shows strong labor productivity improvements across metrics such as throughput time, unit cost, and task effectiveness. However, the distribution of gains is asymmetric in favor of a few companies. While the current distribution of gains does not provide evidence of a power law effect, the current asymmetry reflects differences in AI resources/capabilities across companies - mainly data access, AI talent, or AI governance.

Effect of polyphenols on inflammation related to cognitive function: a systematic review and meta-analysis of human randomized controlled trials

BACKGROUND: The decline of cognitive function could in part be caused by an increase in inflammation. Polyphenols have been widely investigated due to their anti-inflammatory property which may promote therapeutic effects on the brain and cognitive performance. OBJECTIVE: To evaluate the impact of polyphenols interventions on inflammation related to cognitive function in humans. METHODS: Three electronic databases: PubMed/Medline, Web of Science and PsycINFO were systematically searched until 30th May 2024 to find the study that have investigated the effect of polyphenols on both inflammatory response and cognitive function in human randomized controlled trials. The outcomes were pooled and calculated using inverse variance as mean difference (MD) with 95% confidence intervals (95% CI) for the inflammatory markers and standardized mean difference (SMD) with 95% CI for cognitive domains. RESULTS: Ten studies (451 participants, aged 20–81 years) assessed inflammatory markers and cognitive standardized tests responding to polyphenols interventions were included in this review and meta-analysis. Supplementation with polyphenols demonstrated a significant improvement of verbal memory (SMD: 0.33, 95% CI: 0.12 to 0.54, P = 0.002), executive function (SMD: 0.38, 95% CI: 0.03 to 0.72, P = 0.03) and attenuation in blood interleukin-6 (MD: – 1.23 pg/ml, 95% CI: –2.34, to –0.12, P = 0.03). No significant differences were observed in working memory (SMD: 0.13, 95% CI: –0.18 to 0.44, P = 0.42), attention (SMD: –0.19, 95% CI: –0.84 to 0.46, P = 0.57), and psychomotor skill (SMD: 0.09, 95% CI: –0.32 to 0.50, P = 0.66) as well as in c-reactive protein (MD: –0.10 mg/l, 95% CI: –0.28 to 0.09, P = 0.30), and tumor necrosis factor-α (MD: 0.11 pg/ml, 95% CI: –1.25 to 1.47, P = 0.87). CONCLUSION: Polyphenols supplementation decreases blood IL-6 as well as enhances verbal memory and executive function. Regular polyphenols consumption might prevent inflammation related to cognitive decline.

Artificial Intelligence in Employee Learning Process: Insights from Generation Z

Abstract Artificial intelligence, as a field of computer science focused on developing technologies that simulate intelligent behaviours and human cognitive functions, undoubtedly has huge potential to transform all business activities, including the process of employee learning. However, different generations have varying attitudes toward the rapid advancement of technology and the increasing possibilities offered by artificial intelligence. The general purpose of this research is to gain insights into the attitudes of Generation Z regarding the use of AI in the context of the employee learning process. Empirical research was conducted on a sample of 264 respondents from Slovenia and Bosnia and Herzegovina. In addition to descriptive statistics, Cronbach's alpha, Shapiro-Wilk, and Mann-Whitney tests were used to test hypotheses. Generally, the research findings indicate that the upcoming generation of the workforce considers artificial intelligence a significant factor in improving the employee learning process. The study contributes to human resource management literature because it brings new insights into Generation Z attitudes, whose participation in the active workforce will significantly increase in the coming years.

Noninvasive neurostimulation promotes working memory performance in older adults: a systematic review

Working memory is a core component of high-level cognitive functions. A key feature of cognitive decline in older adults is the impairment of working memory capacity, which is also observed in many clinical conditions. In recent years, noninvasive neurostimulation techniques have garnered extensive research attention for their potential to enhance human cognitive function, particularly in older adults. This review focuses on several advanced noninvasive neurostimulation techniques for working memory in older adults. A systematic search of the PubMed and Google Scholar literature databases was conducted, covering research papers published from 2013 to 2023. This review identified 19 articles on transcranial electrical stimulation, 6 on transcranial magnetic stimulation, and 2 on transcranial photobiomodulation techniques that met the inclusion criteria. These results suggest that transcranial electrical stimulation, especially transcranial alternating current stimulation and transcranial direct current stimulation, can improve working memory performance in healthy older adults. Transcranial direct current stimulation combined with cognitive training improves functional connectivity between relevant brain regions in addition to performance gains. Transcranial random noise stimulation, transcranial magnetic stimulation, and transcranial photobiomodulation also have the potential to improve working memory. Further research is needed to understand the neural mechanisms involved and optimize stimulation parameters. In addition, emerging techniques such as transcranial focused ultrasound may offer promising solutions for future studies on working memory enhancement in older adults.

Unmodulated 40 Hz Stimulation as a Therapeutic Strategy for Aging: Improvements in Metabolism, Frailty, and Cognitive Function in Senescence-Accelerated Prone 10 Mice.

With aging populations in many countries, including Japan, efforts to mitigate the aging-related decline in physical function have gained importance not only for improving individual quality of life but also for mitigating the effects of this loss of function on society. Impaired glucose tolerance, muscle weakness, and cognitive decline are well-known effects of aging. These interrelated factors can create a vicious cycle because impaired glucose tolerance can accelerate muscle weakness and cognitive decline. Unmodulated 40 Hz (u40Hz) stimulation is imperceptible to the human ear and has been reported to improve cognitive function in humans and mice. However, research on the effects of u40Hz stimulation is still limited. This study aimed to report the effects of u40Hz stimulation on glucose tolerance and muscle strength in senescence-accelerated prone (SAMP)-10 mice, a model of accelerated aging. SAMP-10 mice underwent five weeks of u40Hz stimulation followed by glucose-tolerance tests, cognitive and behavioral assessments, and frailty evaluations. In comparison with the control group, the u40Hz-stimulation group showed mitigation of age-related decline in glucose tolerance, a better frailty index (FI), and notably preserved muscle strength. Microarray analysis of stimulated muscle tissue revealed significant upregulation of β-oxidation genes and genes functioning downstream of peroxisome proliferator-activated receptor gamma, and significant downregulation of clock genes. These findings indicate the beneficial effects of u40Hz stimulation on glucose tolerance, muscle strength, and cognitive function, warranting further research in this area.

The environmental model of mindfulness

This paper introduces the environmental model of mindfulness, a novel perspective that conceptualizes mindfulness as an adaptive set of cognitive styles influenced by specific socioecological contexts. Extending upon existing conceptualizations of mindfulness as a cultivated trait or practice, the environmental model describes how mindfulness can also result from cognitive adaptations to immediate-return environments. Through an interdisciplinary synthesis of cognitive psychology, anthropology, and environmental studies, four key factors are identified that foster mindful cognitive styles in immediate-return environments: immediate feedback, observational learning, nature exposure, and interconnected self-construal. By examining Indigenous communities living in immediate-return environments, this paper demonstrates how modern, delayed-return environments may inadvertently suppress innate mindful awareness, suggesting that mindfulness practices might be attempts to recalibrate toward more natural cognitive styles. The environmental model bridges Western medical and Eastern ethical perspectives on mindfulness, offering a unifying framework that acknowledges cognitive, environmental, and cultural influences. This approach not only enriches our understanding of human cognitive functioning but also broadens cultural perspectives on mindfulness, highlighting its manifestations across diverse sociocultural contexts. The model has profound implications for mindfulness research and interventions, providing a foundation for more ecologically valid and culturally sensitive approaches to fostering wellbeing. It invites a fundamental reconsideration of the relationship between human cognition and the environment, potentially revolutionizing our approach to mental health and cognitive enhancement in an increasingly complex world. This paper stands as a call to action for researchers, clinicians, and policymakers to rethink fundamental assumptions about human cognition and design environments that support our innate capacity for mindful awareness.

AI in microbiome research: Where have we been, where are we going?

Mushroom-legume-based alternative chicken nuggets: Physico-chemical and sensory properties

The consumer demand for meat analogs (MAs) is on the rise. Soy proteins are frequently used as the primary ingredient in MAs, but soybean may negatively impact human health and cognitive functions. The aim of this research was to develop alternative chicken nuggets using mushroom and chickpea flour. Effect of different sources of mushroom and starch in the textural and sensory quality of nuggets were determined. Phoenix mushroom was chosen based on nuggets' textural and sensory qualities. Different ratios of mushroom and chickpea flour (0:70, 15:55, 55:15, and 70:0, w/w) were tested to prepare the nuggets. Based on protein, textural and sensory qualities compared to chicken and commercial plant-based nuggets, the mushroom to flour ratio of 55:15 was chosen. The results showed that tapioca starch-containing nuggets had a better texture and were more palatable to consumers. The processed nuggets demonstrated lower protein (6.88 vs 11.72%, dry wt. basis) but better cooking yield (87.65 vs 85.29%), moisture retention (77.86 vs 75.16%), fat retention (90.55 vs 88.39%) and higher consumer acceptability than commercially available soy-based nuggets. The results of the study suggest that mushroom and chickpea flour may replace soy protein in meat analogs.

In silico prediction of physicochemical properties and drug-likeness of omega-3 fatty acids

Abstract Omega-3 fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), are recognized for their crucial roles in human health, particularly cardiovascular and cognitive function. In this study, we employed computational methodologies, leveraging the SwissADME platform and ADMETLab 3.0, to predict and cross-validate the physicochemical properties and drug-likeness of these essential fatty acids. SwissADME predictions indicated molecular weights of 278.43 g/mol for ALA, 302.45 g/mol for EPA, and 328.49 g/mol for DHA, with consensus Log Po/w values of 5.09, 5.50, and 5.72 respectively, and varying degrees of water solubility. However, predictions from ADMETLab 3.0 were almost similar: ALA with a molecular weight of 278.22 g/mol, EPA at 302.22 g/mol, and DHA at 328.24 g/mol. Significant discrepancies were observed in lipophilicity, with ADMETLab 3.0 predicting Log Po/w values of 6.461 for ALA, 6.477 for EPA, and 7.006 for DHA, higher than those from SwissADME. Additionally, water solubility predictions from ADMETLab 3.0 showed ALA with a Log S of −5.034, EPA at −4.4, and DHA at −4.638, which differed from SwissADME’s estimates. These differences reflect variations in computational approaches and algorithms. Comparison with literature data revealed general alignment in physicochemical properties, such as water solubility and lipophilicity. Furthermore, assessment of drug-likeness according to Lipinski’s rule demonstrated compliance for all three fatty acids, albeit with variations in other criteria such as Ghose, Veber, Egan, and Muegge rules. These findings underscore the reliability and applicability of computational approaches in elucidating the physicochemical properties and drug-likeness of omega-3 fatty acids, offering valuable insights for pharmaceutical research and therapeutic applications.

Deployment of AI Tools and Technologies on Academic Integrity and Research

Academic integrity is a set of ethical ideals and values that guide the behavior of individuals in academic and educational settings. It encompasses honesty, trustworthiness, fairness, and a commitment to upholding the highest standards of ethical conduct in the quest for knowledge, learning, and research. Academic integrity is essential in maintaining the trustworthiness, reputation, and effectiveness of educational institutions and scholarly communities. Whereas, AI, or Artificial Intelligence, is a broad field of computer science that focuses on creating frameworks, software, or machines that can perform tasks that would typically require human intelligence. These tasks include problem-solving, learning from experience, understanding natural language, recognizing patterns, and making choices. AI systems aim to mimic or replicate human cognitive functions, and they can range from simple rule-based systems to highly complex, autodidactic neural networks. AI can significantly impact academic integrity and research in both positive and potentially challenging ways.

Electroencephalography as a new diagnostic technology for mild psychoneurological disorders

Owing to the increase in the information load in modem society, assessing the clinical characteristics of borderline psychopathological conditions is significantly difficult because we cannot objectively assess them using functional examination methods. To demonstrate the possibility of mathematical analysis of electroencephalography as a new method of clinical electroencephalographic diagnostics for clinically mild conditions, we examined the electroencephalogram indicators of patients who voluntarily and for the first time sought medical help with minimally pronounced clinical manifestations of psychoneurological diseases. The results obtained allowed us to determine that using modern methods of mathematical processing of electroencephalographic signals, we can identify objective differences in the activity indicators of individual cortical structures. The conducted studies allow us to provide practical medicine with a new objective approach to studying human cognitive function.
