区分物种和识别个体的能力对于大多数动物的繁殖成功和/或生存至关重要。然而，这些决策过程的时间顺序和神经定位仍不清楚。在这项研究中，测量了音乐蛙 Nidirana daunchina 的端脑、间脑和中脑的事件相关电位 (ERP)。这些 ERP 是由 1 组异种生物（从同域无尾物种记录）和 2 组基本频率不同的同种生物的叫声引起的。就 ERP 波形内的极性和位置而言，听觉 ERP 通常由 4 个主要组成部分组成，分别与选择性注意 (N1)、刺激评估 (P2)、识别 (N2) 和分类 (P3) 相关。这些分别发生在刺激开始后 100、200、250 和 300 毫秒左右。我们的结果表明，异种叫声和同种叫声之间的 N1 幅度存在显着差异，但基频不同的 2 组同种叫声之间的 N1 幅度没有显着差异。另一方面，两组同种叫声之间的 N2 幅度显着不同，这表明音乐蛙首先区分物种，然后进行个体识别，因为 N1 和 N2 分别与选择性注意和刺激识别有关。此外，女性诱发的P2振幅显着大于男性，表明听觉辨别中存在性别二态性。此外，左侧间脑的N1波幅和左侧端脑的P2波幅均大于其他脑区，表明左半球在听觉感知中占主导地位。总而言之，我们的结果支持这样的假设：物种歧视和个体特征的识别是按顺序完成的，并且听觉感知表现出性别和空间优势之间的差异。
The ability to discriminate species and recognize individuals is crucial for reproductive success and/or survival in most animals. However, the temporal order and neural localization of these decision-making processes has remained unclear. In this study, event-related potentials (ERPs) were measured in the telencephalon, diencephalon, and mesencephalon of the music frog Nidirana daunchina. These ERPs were elicited by calls from 1 group of heterospecifics (recorded from a sympatric anuran species) and 2 groups of conspecifics that differed in their fundamental frequencies. In terms of the polarity and position within the ERP waveform, auditory ERPs generally consist of 4 main components that link to selective attention (N1), stimulus evaluation (P2), identification (N2), and classification (P3). These occur around 100, 200, 250, and 300 ms after stimulus onset, respectively. Our results show that the N1 amplitudes differed significantly between the heterospecific and conspecific calls, but not between the 2 groups of conspecific calls that differed in fundamental frequency. On the other hand, the N2 amplitudes were significantly different between the 2 groups of conspecific calls, suggesting that the music frogs discriminated the species first, followed by individual identification, since N1 and N2 relate to selective attention and stimuli identification, respectively. Moreover, the P2 amplitudes evoked in females were significantly greater than those in males, indicating the existence of sexual dimorphism in auditory discrimination. In addition, both the N1 amplitudes in the left diencephalon and the P2 amplitudes in the left telencephalon were greater than in other brain areas, suggesting left hemispheric dominance in auditory perception. Taken together, our results support the hypothesis that species discrimination and identification of individual characteristics are accomplished sequentially, and that auditory perception exhibits differences between sexes and in spatial dominance.
