Brain oxygenation patterns during the execution of tool use demonstration, tool use pantomime, and body-part-as-object tool use [PDF]

, 2015
© 2015 Elsevier B.V. Divergent findings exist whether left and right hemispheric pre- and postcentral cortices contribute to the production of tool use related hand movements. In order to clarify the neural substrates of tool use demonstrations with tool

Validation of the fNIRS Pioneer™, a Portable, Durable, Rugged functional Near-Infrared Spectroscopy (fNIRS) Device

Proceedings of the 12th International Joint Conference on Biomedical Engineering Systems and Technologies, 2019
Assessing cognitive workload using functional near-infrared spectroscopy (fNIRS) in labs is well established. However, fNIRS sensors useful during normal activities in real-world environments are only recently emerging. We validated a small, portable fNIRS sensor (the fNIRS Pioneer TM) against a larger sensor with coverage of a larger cortical area ...

Application of X-ray photoelectron spectroscopy (XPS) and a functional near infrared spectroscopy (fNIRS) in medicine [PDF]

European Journal of Translational and Clinical Medicine, 2021
The development of modern clinical medicine and the truthful medical diagnosis require hard physicochemical data. Furthermore, the social demands for more accurate and collected data, which refer to human health in real conditions and in real time, force the quest for techniques which would be possible to be applied in a broadly understood clinical ...

An Embedded Auto-Calibrated Offset Current Compensation Technique for PPG/fNIRS System [PDF]

arXiv, 2023
Usually, the current generated by the photodiode proportional to the oxygenated blood in the photoplethysmography (PPG) and functional infrared spectroscopy (fNIRS) based recording systems is small as compared to the offset-current. The offset current is the combination of the dark current of the photodiode, the current due to ambient light, and the ...

Applications and Challenges of Auditory Brain‐Computer Interfaces in Objective Auditory Assessments for Pediatric Cochlear Implants

Exploration, EarlyView.
Auditory brain‐computer interface connects the brain with external devices and decodes neural signals related to auditory perception. Time‐domain and frequency‐domain analyses are commonly used to identify biomarkers associated with auditory rehabilitation, such as cortical auditory evoked potentials and mismatch negativity.

Mapping the landscape of brain stimulation research: A global scientometric review on cognitive impairment

Ibrain, EarlyView.
This study maps global trends in brain stimulation research for cognitive impairment using bibliometric analysis of 4156 records (1989–2024, WoSCC). Findings highlight the dominance of transcranial magnetic stimulation (TMS) and repetitive TMS (rTMS), emerging vascular‐focused research, and promising techniques like fast gamma magnetic stimulation and ...
