Background Attention plays a vital part in the cognitive process, where different kinds of attention are associated with separate brain mechanisms. The objective this research was to investigate patterns activation and functional connectivity middle-aged elderly individuals while they were engaged various attentional tasks, intention establishing reference foundation for clinical treatment disorders. Material methods A total 44 healthy persons (47.1% women) aged over 40 enrolled study. digital cancellation test (DCT), paced auditory serial addition (PASAT), Stroop colour-word test, trail making (TMT) respectively four types tasks: sustained attention, divided selective shifting. Functional near-infrared spectroscopic imaging employed measure concentration oxyhaemoglobin subjects performing these tasks. Results In our study, we found distinct areas such as BA-3, BA-4, BA-6, others. analysis revealed that frontal right parietal lobes consistently showed higher density strength connections across PASAT task exhibiting highest number exceeding threshold. Notably, DCT demonstrated significant correlations oxygen fluctuations among several regions, TMT-B highlighted strong within bilateral lobes. Conclusions This provides evidence people have suggesting individualized disorder patients based on impairment type location. Trial registration: study has been registered through Chinese Clinical Registry (ChiCTR2400087755).

The analysis of human gait is a cornerstone in diagnosing and monitoring variety neuromuscular orthopedic conditions. Recent technological advancements have paved the way for innovative methodologies that combine multimodal neuroimaging eXtended Reality (XR) technologies to enhance precision applicability analysis. This review explores state-of-the-art solutions an advanced approach, multidisciplinary concept integrates neuroimaging, extended reality technologies, sensor-based methods study locomotion. Several wearable modalities such as functional near-infrared spectroscopy (fNIRS) electroencephalography (EEG), commonly used monitor analyze brain activity during walking explore neural mechanisms underlying motor control, balance, adaptation, were considered. XR including virtual, augmented, mixed reality, enable creation immersive environments analysis, real-time simulation, movement visualization, facilitating comprehensive assessment locomotion its biomechanical dynamics. approach enhances understanding by examining both cerebral aspects, offering insights into brain–musculoskeletal coordination. We highlight potential provide real-time, high-resolution data improved clinical decision-making rehabilitation strategies. Additionally, we address challenges integrating these fusion, computational demands, scalability. concludes proposing future research directions leverage artificial intelligence further optimize imaging applications ultimately driving their translation from laboratory settings practice. synthesis underscores transformative approaches personalized medicine patient outcomes.
