NIf nucleus lesion effect on birdsong complexity in adult Bengalese finches (Lonchura striata)
摘要
Abstract
The spectrogram of recorded birdsongs was analyzed in the present study,birdsong features were compared in pre-and post-lesion adult male Bengalese finches.Birdsong complexity in phrase-level was found to decrease.One syllable was distorted and became similar to the other one.At 30th day post-lesion, non-typical songs lost largely and were generally shortened.After-lesion-songs showed more noise that their feature statistics;mean frequence increased,but entropy reduced.Bilateral lesion of NIf nuclei was found to reduce birdsong variations,suggesting that NIf is involved in song complexity,and plays an important role in song production.关键词
