Aging disrupts neural timing, reducing the nervous system's ability to precisely encode sound. Given that the neural representation of temporal features is strengthened with musical training in young adults, can musical training offset the negative impact of aging on neural processing? By comparing auditory brainstem timing in younger and older musicians and nonmusicians to a consonant-vowel speech sound /da/. we document a musician's resilience to age-related delays in neural timing.
衰老破坏了神经计时,降低了神经系统精确编码声音的能力。鉴于在年轻成年人中进行音乐训练可以增强时间特征的神经表现,那么音乐训练是否可以抵消衰老对神经处理的负面影响呢?通过比较年轻音乐家、老年音乐家和非音乐家对浊辅音/da/的听觉脑干计时,我们记录了音乐家对与年龄相关的神经计时延迟的恢复能力。
