人类听众对熟悉的音乐表现出明显的敏感性，也许最容易通过流行的“命名调”游戏来揭示，在这种游戏中，听众通常会成功地识别出基于非常简短的呈现的熟悉歌曲。在这项工作中，我们使用脑电图（EEG）和瞳孔测量法来揭示大脑过程的时间特征，从而区分熟悉，喜欢和不熟悉的音乐片段。与先前的工作相比，先前的工作已经量化了瞳孔直径的逐渐变化（所谓的“瞳孔扩张响应”），在这里，我们专注于瞳孔扩张事件的发生。这种方法在时间域中更加敏感，并允许我们利用假定的显著性网络挖掘早期活动。参与者（N = 10）被动地听片段（750毫秒）的一个熟悉的，个人相关的，声学匹配，不熟悉的歌曲，随机顺序。一组控制参与者（N = 12），谁是不熟悉的所有歌曲，也进行了测试。我们揭示了熟悉和不熟悉的歌曲片段之间的快速分化：瞳孔反应显示，从刺激后100-300毫秒熟悉的音乐更大的扩张率，与更快激活的自主显着性网络相一致。脑反应与脑电图测量显示，后来的分化熟悉和不熟悉的音乐从350毫秒后发病。值得注意的是，在EEG反应中识别的集群模式与经典的旧/新记忆检索范式中常见的模式非常相似，这表明对简短的随机呈现的音乐片段的识别借鉴了类似的过程。
Human listeners exhibit marked sensitivity to familiar music, perhaps most readily revealed by popular “name that tune” games, in which listeners often succeed in recognizing a familiar song based on extremely brief presentation. In this work, we used electroencephalography (EEG) and pupillometry to reveal the temporal signatures of the brain processes that allow differentiation between a familiar, well liked, and unfamiliar piece of music. In contrast to previous work, which has quantified gradual changes in pupil diameter (the so-called “pupil dilation response”), here we focus on the occurrence of pupil dilation events. This approach is substantially more sensitive in the temporal domain and allowed us to tap early activity with the putative salience network. Participants (N = 10) passively listened to snippets (750 ms) of a familiar, personally relevant and, an acoustically matched, unfamiliar song, presented in random order. A group of control participants (N = 12), who were unfamiliar with all of the songs, was also tested. We reveal a rapid differentiation between snippets from familiar and unfamiliar songs: Pupil responses showed greater dilation rate to familiar music from 100–300 ms post-stimulus-onset, consistent with a faster activation of the autonomic salience network. Brain responses measured with EEG showed a later differentiation between familiar and unfamiliar music from 350 ms post onset. Remarkably, the cluster pattern identified in the EEG response is very similar to that commonly found in the classic old/new memory retrieval paradigms, suggesting that the recognition of brief, randomly presented, music snippets, draws on similar processes.
