| Research Abstract |
Today, most of the environmental information surrounding urban people in their daily lives is artificially provided. Based on the standpoint of the environmental informatics, in which we proposed that "effects of information on human body is equivalent to those of matter", we measured the gene expression dynamics using the micro-array analysis to examine the effects of audio-visual information provided by media on human body as an objective physiological index.
We examined how the difference in density of images and sounds affect gene expression of people perceiving information. In the experiments, we presented visually both the 4K-standard image and the 2K-standard image. For audio stimulation, both the High-Cut Sound which did not contain the high-frequency components above 22 kHz, and the Full-Range Sound which contained ultra wide range frequency including high-frequency components above 22KHz. We measured the gene expression dynamics when subjects perceived audio-visual information with various combinations. In addition, we also simultaneously measured the electroencephalogram and the biologically active substances in blood.
As a result, clear differences in gene expression were observed between the higher-density information and the lower-density one. The measurement of electroencephalogram and the biologically active substances in blood suggested that high-density information had a tendency to induce comforts, which was consistent with our previous reports. The tendency was observed more remarkably in the comparison of sound information than in that of visual information.
For the future study, we will further clarify the detailed function of the detected gene in the present study.
