Abstract

Digital plethysmograms of healthy subjects were measured and chaos analyzed. Correlation dimentions calculated with Judd's method were smaller than two in general. They were highest(near2.0)in low aged children and decreased as the subject age increased. Increases of dimensions by the conduction of Nihon Ijyutu were also observed. Measurement of the effect of suggestion or resting etc.are now in progress.
