Ultra-sonic songs in mice:functional analysis of vocal control mechanisms

我们研究了雄性小鼠在超音速歌曲中发声的机制与听觉反馈和动机的关系。我们测量了正常小鼠和转基因小鼠的发声和听觉敏感度之间的关系。我们还损毁了杏仁核，以观察歌曲制作的效果。在钙粘蛋白-6基因敲除小鼠中，交配歌曲的音调增加，但听觉敏感度没有变化。在杏仁核损伤的小鼠中，复杂的元素消失了。

We studied the mechanisms of vocal production in ultra-sonic songs in male mice in relation to auditory feedback and motivation. We measured the relationship between vocal production and auditory sensitivity in normal and genetically modified mice. We also lesioned amygdala to see the effects in song production. In cadherin-6 knockout mice, the pitch increased in mating songs but there were no changes in auditory sensitivity. In amygdale lesioned mice complex elements were disappeared.
