はじめに

　機能的近赤外分光法（functional near-infrared spectroscopy：fNIRS）は近赤外線を用いて，生体内のヘモグロビンの変化量を計測する手法である^1）．fNIRSは測定が簡便であり，侵襲性と肢位の制限が少ないため，臨床現場において使用しやすい機器の1つである．そのため，健常者や脳卒中片麻痺患者を対象にバランス制御時や歩行時の脳活動などの測定が試みられている^2,3）．本稿ではfNIRSの原理や機能的磁気共鳴画像法（functional magnetic resonance imaging：fMRI）との相違を解説し，fNIRSを用いて測定した視覚性運動錯覚の研究を紹介する．
