美國康奈爾大學Joseph R. Fetcho、Chris Xu等研究人員合作開發了用於完整成年斑馬魚大腦的深度三光子成像技術。相關論文於2020年4月27日在線發表在《自然—方法學》雜誌上。
研究人員表明,通過完整成年斑馬魚頭部的三光子(3P)成像可以實現在整個腦末梢以及小腦和視神經頂的細胞解析度結構和功能成像。通過3P成像,在脊椎動物模型中,從胚胎到性成熟的成體,其大部分大腦區域可實現無創觀測。
據介紹,行為來自整個大腦的活動,但是成體脊椎動物大腦的無創光學研究受到限制。

Abstract: Behaviors emerge from activity throughout the brain, but noninvasive optical access in adult vertebrate brains is limited. We show that three-photon (3P) imaging through the head of intact adult zebrafish allows structural and functional imaging at cellular resolution throughout the telencephalon and deep into the cerebellum and optic tectum. With 3P imaging, considerable portions of the brain become noninvasively accessible from embryo to sexually mature adult in a vertebrate model.
