| Research Abstract |
Studies have shown that music confers plasticity to the brain. In a preliminary pilot study, we examined the effect of music listening on steroid hormones and the relationship between steroid hormone receptor polymorphisms and musical ability. Twenty-one subjects (10 males and 11 females) were recruited and divided into musically talented and control groups.
The AMMA scores were higher for the short repeat length-type AR than for the long repeat length-type.Comparisons of AR polymorphisms and T levels before the experiments showed that the T levels were within the low range in the short repeat length-type group and there was a positive relationship with the repeat length, although it was not significant. The AMMA scores were higher for the short repeat length-type AVPR1A (RS1) than for the long repeat length-type, although the differences were not significant.This is the first study of humans to analyze relationships between the AR gene, T levels, and musical ability.
