动物使用各种复杂的信号机制来传达一系列可以被同种动物和异种动物检测到的信息。这些信号的接收者感知该信息并用它来指导他们的后续行动。因此，诸如声音通信信号的发送者和接收者之间发生的通信可以成为研究决策背后的感官知觉和行动启动的神经基础的强大模型。在这项研究中，我们研究了雌性鸣禽如何感知雄性鸣禽发出的声音信号（歌曲）的质量，并利用该信息来表达对多种可能的选择中的一首歌曲的偏好。我们在听觉处理区域（尾部nidopallium，NC）中损伤引起的活动改变之前和之后对歌曲偏好进行行为测量，我们之前已经描述了该区域与其他听觉区域和下游奖励通路的互连。我们的研究结果表明，灭活 NC 不会改变雌性执行择偶行为指标的能力或意愿，也不会改变它们识别单个雄性歌曲的能力。然而，NC 损伤确实会导致特定男性的歌曲偏好强度比其他男性更严重。这种减少并不会导致偏好的完全消除，因为女性对特定男性的偏好仍然很明显，但在 NC 病变后表现得不那么强烈。总而言之，这些数据表明 NC 在歌曲评估和择偶方面对雌性的偏好强度发挥着重要作用，而 NC 的活动是择偶的一个重要方面。
Animals use a variety of complex signaling mechanisms to convey an array of information that can be detected by conspecifics and heterospecifics. Receivers of those signals perceive that information and use it to direct their subsequent actions. Thus, communication such as that which occurs between senders and receivers of vocal communication signals can be a powerful model in which to investigate the neural basis of sensory perception and action initiation that underlie decision-making. In this study, we investigated how female songbirds perceive the quality of acoustic signals (songs) performed by males and use that information to express preference for one song among many possible alternatives. We use behavioral measurement of song preference before and after lesion-induced alteration of activity in an auditory processing area (caudal nidopallium, NC) for which we have previously described its interconnections with other auditory areas and downstream reward pathways. Our findings reveal that inactivating NC does not change a female’s ability or willingness to perform behavioral indicators of mate choice, nor does it change their ability to identify the songs of individual males. However, lesioning NC does induce a decrease in the strength of song preference for specific males more than others. That decrease does not result in a complete elimination of preference, as female preferences for specific males are still evident but not as strongly expressed after lesioning of NC. Taken together, these data indicate that NC plays a role in a female’s strength of preference in song evaluation and mate choice, and activity in NC is an important facet of mate choice.
