We propose to set up such a multi-disciplinary team to tackle this question with experts and resources from National Taiwan University and the University of Southern California including researchers in the fields of developmental biology, ophthalmology, neurobiology, and animal behavior. The investigations include four parts executed by the research groups from both sides, i.e. (1) learning and setting up the bird platform for cognition studies – including depicting the cognition pathway of the Displayer – Sensor – Processor axis, learning developmental biology and gene transduction for birds, and learning the technique of generating transgenic quail and establish the technical platform on the finch, (2) analyses of the displayer – the sexually dimorphic pigment patterns and feather forms, (3) analyses of the sensor – retina, with the analysis of photoreceptor distribution and electroretinogram (ERG), (4) analyses of the processor – brain, with a three-tiered approach: electrophysiology for crude mapping (LFP and EEG), immunohistochemistry with c-Fos for finer mapping, and calcium imaging for high resolution mapping. We expect the close collaboration among the research groups ensures the inter-connection of the four investigation directions that are helpful for achieving significant advance in the transgenic avian research platform and related research work.基因轉殖鳥禽視覺處理認知神經迴路transgenic avianvisual processcognitionneural circuits利用基因轉殖鳥類研究視覺處理模式及認知行為(1/2)
