FRAGRANCE CHEMICALS ON ENHANCING CONCENTRATION STATE OF BRAIN FUNCTION BY DECREASING ABSOLUTE LOW BETA POWER SPECTRUM AT LEFT PREFRONTAL REGION (FP1), INCREASING ABSOLUTE HIGH BETA POWER SPECTRUM AT RIGHT PARIETAL REGION (P4), AND INCREASING RMT INDEX AT LEFT (P3) AND RIGHT PARIETAL REGIONS (P4)

摘要

The present invention relates to a fragrance composition for enhancing concentration by statistically and significantly decreasing absolute low beta power spectrum at left prefrontal region (Fp1), statistically and significantly increasing absolute high beta power spectrum at right parietal region (P4), and statistically increasing ratio of mid beta to theta (RMT) index at left (P3) and right parietal regions (P4). More specifically, combination spices consisting of lavender oil, lemon oil, basil oil, bergamot oil, vetive oil, acorus oil, patchouli oil, petitgrain oil, methyl ionone gamma, benzyl acetate, citral, evernyl, eugenol, coumarin, hedion, hexyl cinnamic aldehyde, and helional have citrus, coniferous, green, herbal, minty, oily, powdery, and spicy fragrances.
