Unlabelled: Recent studies suggest that executive functions are among the first cognitive functions to decline with normal aging.
Methods: We studied the effect of age on executive functions using a set of 13 arithmetic word problems including 9 problems of increasing complexity which were solvable in 2, 3, 4 operations, and 4 aberrant problems. Three groups participated in the study: 18 young, 18 adult and 18 elderly participants.
Results: The results showed that elderly participants were more impaired to resolve complex arithmetic word problems, without deficit in their ability to eliminate aberrant problems.
Conclusion: The current elderly sample has a dissociated pattern of performance similar to that of some patients with frontal lobe lesions. In these patients, relations were found between the inability to generate correct algorithms of resolution for arithmetic word problems of increasing complexity and lesions in the dorsolateral prefrontal cortex, and between the impaired inhibition of unsolvable word problems and lesions in the orbitofrontal regions. We suggest that cognitive aging could be better interpreted in terms of changes in some frontal systems rather than in all-encompassing frontal deterioration.

Background: Patients who are informed about the causes, pathophysiology, treatment and prevention of a disease are better able to participate in treatment procedures in the event of illness. Artificial intelligence (AI), which has gained popularity in recent years, is defined as the study of algorithms that provide machines with the ability to reason and perform cognitive functions, including object and word recognition, problem solving and decision making. This study aimed to examine the readability, reliability and quality of responses to frequently asked keywords about low back pain (LBP) given by three different AI-based chatbots (ChatGPT, Perplexity and Gemini), which are popular applications in online information presentation today.

Music generation by AI algorithms like Transformer is currently a research hotspot. Existing methods often suffer from issues related to coherence and high computational costs. To address these problems, we propose a novel Transformer-based model that incorporates a gate recurrent unit with root mean square norm restriction (TARREAN).
