報告二題目：感知與抉擇的神經環路運算

報告人：徐寧龍　博士生導師，研究員

報告人介紹：

1999-2006   中國科學院神經科學研究所   博士
2006-2008   美國冷泉港實驗室   博士后

2008-2013   美國 HHMI Janelia Research Campus 博士后

2013-至今     中科院上海生科院神經科學研究所   研究員

主要研究方向：

  1.  我們在執行聽覺感知抉擇任務的小鼠中，使用雙光子顯微鏡觀察大腦皮及皮層下神經元的電信號，以揭示聽覺感知與行為抉擇的神經編碼原理；

2.  我們使用光遺傳學和化學遺傳學等神經環路干預技術，揭示各個腦區及它們之間形成的環路在感知與抉擇中的作用機制；

3.  我們與人工智能研究人員合作，探索如何將動物面對復雜感覺信息進行行為抉擇的神經計算原理應用于機器智能技術開發。
