声音交流在大多数两栖动物的生存和繁殖成功中起着至关重要的作用。虽然两栖动物的交流声音往往是复杂的，包括许多时间特征，我们知道的生物学意义的每一个时间组成部分。采用优化的失匹配负波（MMN）脑电图（EEG）范式，研究了峨眉乐蛙（Babina daunchina）雄性广告叫声的生物学意义。音乐蛙的叫声通常包含4到6个音符，间隔约为150毫秒。一个标准的刺激（白色噪声）和五个偏离刺激（五个音符，从一个广告电话），同时记录多通道EEG信号播放到每个主题。结果表明，第一个呼叫音符的MMN振幅显著大于其他音符。此外，从左前脑和中脑诱发的MMN振幅通常大于从右对应。这些结果是一致的想法，即第一个电话注意到传达更多的信息比其他人的听觉识别，并有左半球的优势，处理来自同种的呼叫青蛙的信息。
Vocal Communication plays a crucial role in survival and reproductive success in most amphibian species. Although amphibian communication sounds are often complex consisting of many temporal features, we know little about the biological significance of each temporal component. The present study examined the biological significance of notes of the male advertisement calls of the Emei music frog (Babina daunchina) using the optimized electroencephalogram (EEG) paradigm of mismatch negativity (MMN). Music frog calls generally contain four to six notes separated approximately by 150 millisecond intervals. A standard stimulus (white noise) and five deviant stimuli (five notes from one advertisement call) were played back to each subject while simultaneously recording multi-channel EEG signals. The results showed that the MMN amplitude for the first call note was significantly larger than for that of the others. Moreover, the MMN amplitudes evoked from the left forebrain and midbrain were typically larger than those from the right counterpart. These results are consistent with the ideas that the first call note conveys more information than the others for auditory recognition and that there is left-hemisphere dominance for processing information derived from conspecific calls in frogs.
