Recent applications of EEG-based brain-computer-interface in the medical field

Military Medical Research, Год журнала: 2025, Номер 12(1)

Опубликована: Март 24, 2025

Abstract Brain-computer interfaces (BCIs) represent an emerging technology that facilitates direct communication between the brain and external devices. In recent years, numerous review articles have explored various aspects of BCIs, including their fundamental principles, technical advancements, applications in specific domains. However, these reviews often focus on signal processing, hardware development, or limited such as motor rehabilitation communication. This paper aims to offer a comprehensive electroencephalogram (EEG)-based BCI medical field across 8 critical areas, encompassing rehabilitation, daily communication, epilepsy, cerebral resuscitation, sleep, neurodegenerative diseases, anesthesiology, emotion recognition. Moreover, current challenges future trends BCIs were also discussed, personal privacy ethical concerns, network security vulnerabilities, safety issues, biocompatibility.

Abstract Electrical stimulation of the human brain has emerged as a powerful therapeutic modality, enabling alteration neural circuits underlying cognition and behavior. Recent evidence indicates that stimulation’s effects on physiology behavior depend endogenous variation in state, measured by field-potential recordings. Here, we describe 60-channel brain-computer interface – Smart Neurostimulation System (SNS) combines closed-loop analysis spectral features field potential with multi-channel capabilities. We demonstrate system functionality via bench tests from an vivo ovine study exercising subset device’s functionality. Our shows SNS can reliably measure correlates (motion) physiological stimulation. safety histology following 120-day study.

Advances in Endovascular Brain Computer Interface: systematic review and future implications

Journal of Neuroscience Methods, Год журнала: 2025, Номер 420, С. 110471 - 110471

Опубликована: Май 10, 2025

Brain-computer interfaces (BCIs) translate neural activity into real-world commands. While traditional invasive BCIs necessitate craniotomy, endovascular offer a minimally alternative using the venous system for electrode placement. This systematic review evaluates technical feasibility, safety, and clinical outcomes of BCIs, discussing their future implications. A was conducted per PRISMA guidelines. The search spanned PubMed, Web Science, Scopus databases keywords related to approaches. Studies were included if they reported on in preclinical or settings. Dual independent screening extraction focused material, recording capabilities, safety parameters, efficacy. From 1385 initial publications, 26 met inclusion criteria. Seventeen studies investigated Stentrode device. Among 24 studies, 16 used ovine rodent models, 9 addressed engineering simulation aspects. Two six ALS patients successfully an BCI digital communication. Preclinical data established model, demonstrating stable recordings vascular changes with long-term implantation. Key challenges include thrombosis risk, stability, anatomical variability. Endovascular reduced invasiveness, improved profiles, comparable fidelity methods, promising preliminary severely paralyzed patients. Early results are promising, but remain scarce. Further research is needed optimize signal processing, enhance biocompatibility, refine procedures broader applications.

Endovascular electrode arrays provide a minimally invasive approach to access intracranial structures for neural recording and stimulation. These are currently used as brain-computer interfaces (BCIs) deployed within the superior sagittal sinus (SSS), although cortical vein implantation could improve quality quantity of recorded signals. However, anatomy veins is heterogenous poorly characterised. MEDLINE Embase databases were systematically searched from inception December 15, 2023 studies describing veins. A total 28 included: 19 cross-sectional imaging studies, six cadaveric one intraoperative anatomical study review.
