Research Abstract

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.
