Short-Term Effects of Meditation on Sustained Attention as Measured by fNIRS
Brain Sciences, 2020 Cognitive abilities such as attention, memory, processing time, perception, and reasoning can be augmented using some type of intervention. Within the broad range of conventional and unconventional intervention methods used in cognitive enhancement ...

Noise reduction in functional near-infrared spectroscopy signals by independent component analysis [PDF]
, 2015 Functional near-infrared spectroscopy (fNIRS) is used to detect concentration changes of oxyhemoglobin and deoxy-hemoglobin in the human brain. The main difficulty entailed in the analysis of fNIRS signals is the fact that the hemodynamic response to a ...

Investigation of frontal lobe activation with fNIRS and systemic changes during video gaming. [PDF]
, 2013 Frontal lobe activation caused by tasks such as videogames can be investigated using multichannel near-infrared spectroscopy (fNIRS), sometimes called optical topography. The aims of this study are to investigate the effects of video gaming (fighting and

Monitoring multiple cortical regions during walking in young and older adults: dual-task response and comparison challenges [PDF]
, 2019 Performance of several tasks simultaneously (dual-tasks) is common in everyday walking. Studies indicate that dual-task walking performance declines with age together with cognitive function, but neural mechanisms underpinning deficits remain unclear ...

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 ...

Measurement of Brain Function of Train Driver Using Functional Near-infrared Spectroscopy (fNIRS)
The Japanese journal of ergonomics, 2007 鉄道の安全性確保のために, 列車運転士には判断に関するヒューマンエラーを犯さないことが強く求められる. 列車運行時のヒューマンエラーを防止するためには, 人間の特性を考えた運転支援システムの開発が必要である. このようなシステムを開発するにあたっては, 運転操作と認知, 判断にともなう脳機能に着目する必要がある. 本論文では, 列車運転中の運転士の高次脳機能を, 機能的近赤外分光 (fNIRS) 装置を用いて計測した. 運転中の脳機能活動を抽出するために, ウェーブレット変換による多重解像度解析を適用することを提案した. 運転シミュレータを用いた実験の結果, 提案の方法により運転中の高次脳機能を評価できることを示した.
