Abstract

1. Objectives The objective of this study was to measure the differences of EEG changes accoring to emotional stimulus in Sasangin. 2. Methods 44 healthy volunteers(Soyangin 10, Soeumin 14, Taeumin 20) were participated. Sasang Constitution was diagnosed by Sasang specialist. Volunteers watched horror movie as the emotional stimulus. We recorded EEG data during pre-stimulus rest(120sec), during-stimulus(197sec), rest-stimulus(120sec). Power spectral analysis was done and relitive power and ${\alpha}/{\beta}$ ratio were compared among each groups. 3. Results (1) The mean of relative ${\alpha}$ of Taeumin was significantly decreased according to stimulus compared with Soyagnin. (2) Relative ${\alpha}$ of Soeumin was significantly decreased in T3 area according to stimulus compared with Taeumin. (3) Relative ${\beta}$ of Taeumin group was significantly increased in Fp2 area according to stimulus compared with Soeumin. 4) Relative $high-{\beta}$ of Soyangin group was significantly decreased in F3 by the post-stimulus rest compared with Soeumin. (5) ${\alpha}/{\beta}$ ratio of Soeumin was significantly increased according to stimulus compared with other groups. 4. Conclusions Soyangin showed sensitive changes according to the emotional simulus compared with Soeumin and Taeumin. Above results suggest that the emotional characteristics of Sasangin can be measured by objective methods as by EEG.
