PROBLEM TO BE SOLVED: To propose a transcranial current stimulation device and transcranial current stimulation method, capable of efficiently enhancing or suppressing a brain function with a current value lower than a conventional one.SOLUTION: In a transcranial current stimulation device 11, stimulation current specification means 14 detects a brain wave voltage from a scalp H, converts the brain wave voltage into a stimulation current, and outputs the stimulation current to a predetermined region of the scalp H. Accordingly, a weak stimulation current dependent on the brain wave voltage can be fed to a head through the scalp H while being interlocked with a change in the brain wave voltage. Eventually, a brain function can be efficiently enhanced or suppressed with a current value, which is lower than a conventional one, according to a situation of cranial nerves.COPYRIGHT: (C)2014,JPO&INPIT【課題】効率良く、従来よりも低い電流値で脳機能を促進または抑制し得る経頭蓋電流刺激装置および経頭蓋電流刺激方法を提案する。【解決手段】経頭蓋電流刺激装置11では、刺激電流特定手段14によって、頭皮Hから脳波電圧を検出し、当該脳波電圧を刺激電流に変換してこの刺激電流を頭皮Hの所定の部位に出力するようにしたことにより、脳波電圧の変化に連動して当該脳波電圧に応じた微弱な刺激電流を、頭皮Hを介して頭部に流すことができ、かくして、脳神経の状況に応じて効率良く、従来よりも低い電流値で脳機能を促進または抑制し得る。【選択図】図3
