Motor imagery (MI) electroencephalogram (EEG) signals have an important role in brain-computer interface (BCI) research. However, effectively decoding these remains a problem to be solved. Traditional EEG signal algorithms rely on parameter design extract features, whereas deep learning represented by convolution neural network (CNN) can automatically which is more suitable for BCI applications. when data taken as input raw time series, traditional 1D-CNNs are unable acquire both frequency domain and channel association information. To solve this problem, study proposes novel algorithm inserting two modules into CNN. One the Filter Band Combination (FBC) Module, preserves many features possible while maintaining characteristics of EEG. Another module Multi-View structure that from output FBC module. prevent over fitting, we used cosine annealing with restart strategy update rate. The proposed was validated competition dataset experiment dataset, using accuracy, standard deviation, kappa coefficient.

Abstract Perceiving and modulating emotions is vital for cognitive function often impaired in neuropsychiatric conditions. Current tools evaluating emotional dysregulation suffer from subjectivity lack of precision, especially when it comes to understanding emotion a regulatory or control-based perspective. To address these limitations, this study leverages an advanced methodology known as functional brain controllability analysis. We simultaneously recorded electroencephalography (EEG) magnetic resonance imaging (fMRI) data 17 healthy subjects engaged processing regulation tasks. then employed novel EEG/fMRI integration technique reconstruct cortical activity high spatiotemporal resolution manner. Subsequently, we conducted analysis explore the neural network control patterns underlying different Our findings demonstrated that dorsolateral ventrolateral prefrontal cortex exhibited increased during negative compared neutral emotion. Besides, anterior cingulate was notably more active managing than either controlling regulating Finally, posterior parietal emerged central controller This offers valuable insights into mechanisms support perception regulation.

Cognitive impairment refers to the of higher brain functions such as perception, thinking or memory that affects individual's ability perform daily social activities. Studies have found changes in neuronal activity during tasks patients with cognitive are closely related cerebral cortical hemodynamics. Functional near-infrared spectroscopy is an indirect method measure neural based on blood oxygen concentration cortex. Due its strong anti-motion interference, high compatibility, and almost no restriction participants environment, it has shown great potential research field impairment. Recognizing these benefits, this comprehensive review systematically elucidates rationale, historical development, advantages disadvantages functional spectroscopy, also discusses applications combining other detection techniques. Additionally, summarized how can be applied caused by different diseases, ultimately aiding study mechanisms activities, which crucial for diagnosis, differentiation treatment

Cognitive phenomena such as the Spatial-Numerical Association of Response Codes (SNARC) effect can arise in fronto-parietal cortical network. Prior neuromodulation studies with cathodal transcranial direct current stimulation (tDCS) over left prefrontal cortex (PFC) reduced SNARC effect. neuroimaging functional near-infrared spectroscopy (fNIRS), however, showed signatures posterior parietal (PPC). In this study, we investigated distant neural on hemodynamic activity by combining tDCS fNIRS. The and numerical distance (NDE) were assessed an event-related cross-over design (N = 45), when 1 mA at PFC was applied simultaneously during measurement fNIRS covering bilateral PPC. At behavioral level, did not significantly reduce effect, indicating that replication failed here. Crucially, neuronal activation associated but NDE. This a remote site shown preregistered primary region-of-interest analyses secondary all-channel analyses. results how combination shed light network responsible for cognition, assess effects tDCS.
