For animals, like many fishes, the timing of both the sperm- and egg-release is essential for successful fertilization to occur. In the hime salmon (landlocked red salmon, Oncorhynchus nerka) this is achieved by exchanging signals specific for this purpose between the sexes.In this study, we aimed at clarifying (1) what are the signals and their character which are exchanged between the sexes, (2) what are the sensory systems processing these signals, and (3) how the central nervous system processes these signals to elicit the spawning behavior.The results using both the behavioral and electrophysiological methods showed that the hime salmon exchange between the sexes both the vibrational signals arising from the body vibration and visual signals to elicit the spawning behavior. The vibrational signals are processed through the lateral line system to integrate them with those from the visual signals. Furthermore, it was found that field potentials are evoked from the medial nucleus of the medulla (the first relay station of the vibrational information) which are synchronized with the vibrational stimuli.

对动物来说，像许多鱼类一样，精子和卵子释放的时间对成功受精至关重要。在鲑鱼（内陆红鲑鱼，Oncorhynchus nerka）中，这是通过在两性之间交换特定的信号来实现的。在本研究中，我们旨在澄清(1)两性之间交换的信号及其特征是什么，(2)处理这些信号的感觉系统是什么，(3)中枢神经系统如何处理这些信号以引发产卵行为。行为学和电生理学的研究结果表明，大马哈鱼通过交换身体振动信号和视觉信号来诱导产卵行为。通过侧线系统对振动信号进行处理，使其与视觉信号相结合。此外，还发现从髓质内侧核（振动信息的第一个中继站）诱发的场电位与振动刺激同步。
