科学杂志:熟悉的音乐能"唤醒"大脑

来源: 作者: 发布日期:2021-08-06 访问次数:29

音乐研究已成为神经科学领域的课题.历史上失乐症病人提示了音乐能力与特殊脑区之间的关系.运用新的技术方法,尤其是功能磁共振成像(fMRI)技术,已经对正常人的音乐能力,音乐家的特殊音乐才能,音乐的情绪效应等方面的神经基础有了一定的认识.进一步理解音乐现象的神经基础必将在许多方面推进人类对自身大脑的认识.

Remember scrolling through the radio dial, hoping a tune you liked would pop out of the static?
还记得在收音机上调台,希望你喜欢的曲子突然出现的时候吗?
You never had to listen too long to know you'd landed on a hit.
你不需要太长时间就能听到你想要的歌。
"Music has a really strong, remarkably strong, hold on us.
“音乐对我们的影响非常大,极为强大。
So it's way enough to be exposed to a very brief snippet of a familiar song for us to be able to recognize it."
只要听一小段熟悉的歌曲,我们就能识别出来?!?br /> Maria Chait, an auditory cognitive neuroscientist at University College London.
伦敦大学学院的听觉认知神经学家玛丽亚·柴特说到。
Chait and her team recently studied how quick that reflex is.
柴特及其团队最近研究了这种反应的迅速程度。
熟悉的曲调也触发了两步的大脑激活模式,这与在其他记忆研究中看到的几乎相同——大脑首先识别熟悉的事物,然后检索关于它的更详细的信息。这种模式在不熟悉的歌曲和对照组中是不存在的。
The results are in the journal Scientific Reports.
该研究结果发表在《科学报告》杂志上。
The study does have limitations: it used a small number of songs; it was hard to mask the purpose of the study from the participants; and the control group ended up being primarily international students from Asia—since they had to be unfamiliar with every single song—so their native languages and music backgrounds differed from the experimental group—primarily students from a European background.
这项研究确实有局限性:它只使用了少量的歌曲;很难向参与者隐瞒研究的目的;而对照组主要是来自亚洲的国际学生,因为他们对每首歌都不熟悉,所以他们的母语和音乐背景与实验组不同——实验组主要是来自欧洲的学生。

Still, for clinicians who want to use music as a therapeutic tool for patients with dementia, for example, this study might provide a few clues:
然而,对于想要将音乐作为痴呆患者治疗工具的临床医生来说,这项研究可能会提供一些线索:

“There’s a lot of interest in trying to establish objective measures of music enjoyment, of music familiarity. And this paradigm might be useful in this context, because it doesn’t require the participant to indicate anything. They just listen passively.”
“人们对建立音乐享受和熟悉度的客观衡量标准很感兴趣。这个范例在这种情况下可能是有用的,因为它不需要参与者指示任何东西。他们只是被动地倾听?!?br />
Clinicians simply have to observe the neural fingerprints of hearing that same old song.
临床医生只需要观察听到这首老歌的神经图谱。
