Abstract

Description
デルタ1=V(f2)−V(f1)
[数2]
デルタ2=V(f3)−V(f2)
ここで、f1、f2、f3は周波数を意味し、Vは、各周波数で電圧の強度を意味する。もし、デルタ1が正数値であり、デルタ2が負数値であれば、f2は頂点になる。反復的に同じ周波数で頂点が現れるのは、脳や肉体の特徴的な活動を意味することであり、脳波信号は脳の状態を、筋肉信号はからだの状態を表す。各変曲周波数を人体の各部位と一対一で対応させて人体の健康状態を判断する。状態の軽重は、頂点(変曲点)が現れる頻度数と脳波信号の振幅、脳波信号のFWHMなどにより決定される。もし、変曲点が一定の周波数で開眼及び閉眼時に継続的に現れるならば、症状が激しいと言える。疾病の発生範囲はFWHMにより決定される。もし、FWHMが小さければ局所的であり、大きければ広範囲に広がっていることを意味する。これを数式で表現すれば、次の数式3の通りである。
H(n,V,w)=Af(nV/w)
ここで、nは変曲点の発生頻度数、Vは脳波信号の振幅、wは脳波信号のFWHM、Aは比例定数を意味し、Hは健康(Health)を意味する関数であり、fはnV/wの変数を持つ関数であるという意味である。したがって、一定周波数に対応する人体の対応点での疾病の軽重は変曲点の発生頻度数と脳波信号の振幅に比例し、脳波信号のFWHMに反比例するということである。これはあくまでも線形的な関係式を意味し、さらに非線形的な関係式を考慮してもよい。
VL=(V1−V4)−(V3−V4)
[数5]
VR=(V2−V4)−(V3−V4)
ここで、VLは左脳電位、VRは右脳電位を表し、V1ないしV4は前記各電極の電位を表す。
