What is fNIRS?
Among technologies measuring and visualizing (imaging) brain activity (brain function), fNIRS, which uses near-infrared light, is attracting attention as a method supporting brain-function research because it enables functional brain imaging under conditions close to natural environments. Exploiting its ability to measure brain function noninvasively and with few restraints, fNIRS is used in a broad range of research: basic research such as “functional brain mapping,” linking brain function and structure, as well as medical, rehabilitation, sports-medicine, psychology, education, and engineering research and industrial fields including automobiles and cosmetics. Another major feature is its compatibility with other measurement methods, enabling simultaneous measurement. fNIRS is also sometimes called near-infrared spectroscopy (NIRS), optical topography, or “optical topo.”
fNIRSとは
脳の活動(脳機能)を計測し、可視化(イメージング)する技術の中で、近赤外光を用いたfNIRSは自然に近い環境下で脳機能イメージングが行えるため、脳機能の研究を支える手法のひとつとして注目されています。非侵襲で脳機能計測ができ、また、拘束が少ない特性を利用して、脳の機能と構造を結びつける“脳機能マッピング”等の基礎研究をはじめ、医療研究、リハビリテーション研究、スポーツ医学研究、心理学、教育学、工学分野や自動車、化粧品等の産業分野まで、幅広い研究でfNIRSは活用されています。また、fNIRSは他の計測法との親和性が高いため、同時計測が可能であることも大きな特長です。fNIRSは、近赤外分光法(NIRS)、光トポグラフィー(光トポ)などと呼ばれることもあります。
