The audible range components which is a vibration component in the audible frequency range, and a super high frequency component in the range up to a predetermined frequency exceeding the audible frequency range, and the second property of the predetermined nature of the predetermined first By applying to human actual vibration that includes a means for generating a vibration signal or a vibration with an autocorrelation order represented by the nature of at least one of, were generated from the vibration signal or the vibration to the human fundamental brain activation to activate the fundamental brain network system consisting of a fundamental brain network that projects into the brain based in the fundamental brain and fundamental brain is the site responsible for the core functions of the brain, including the brainstem, thalamus, hypothalamus of I lead the effect.可聴周波数範囲の振動成分である可聴域成分と、上記可聴周波数範囲をこえ所定の最大周波数までの範囲内の超高周波成分とを有し、所定の第1の性質と所定の第2の性質とのうち少なくともいずれかの性質で表される自己相関秩序を有する振動又は振動信号を発生する手段を備え、上記振動又は上記振動信号から発生させた実際の振動を人間に印加することにより、当該人間の脳幹・視床・視床下部を含む脳の基幹的機能を担う部位である基幹脳及び当該基幹脳を拠点に脳内に投射する基幹脳ネットワークからなる基幹脳ネットワーク系を活性化する基幹脳活性化効果を導く。
