Abstract (in Japanese) (See Japanese page) 
(in English) This study quantitatively evaluated the degree of excitement during race viewing using β/α ratio of Electroencephalography as an index, in order to neuroscientifically elucidate the appeal of horse racing, which has attracted attention in recent years. Measurements were conducted on 20 males and females in their 20s by presenting a video of a horse race under a condition of cheering for a specific horse. As a result, the β/α ratio increased statistically significantly during the race compared to the resting state. Furthermore, in a comparison of a section that horses run twice, it was confirmed that the β/α ratio in the final straight section of the second lap increased statistically significantly compared to that of the first lap, which is the beginning of the race. This trend was prominent in participants with race viewing experience and limited in novices.
