an isolated retinal preparation to record light response from genetically labeled retinal ganglion cells

在脊椎动物视觉第一步骤，当光线刺激视网膜 1杆和锥光感受器。然后将这些信息分割成ON和OFF通路。光感受器信号光信息的双极细胞（BCS），其中光照强度的增加（BCS）的或减少（关BCS）去极化响应。这种光信息的隔离是保持在视网膜神经节细胞（RGC的），其中有分层内网状层（IPL），他们收到来自关闭的BC直接兴奋输入关sublamina的树突的水平，或分层在sublamina的彩光，他们收到直接的兴奋性输入在边界条件。这隔离的关于增加或减少照明（开启和关闭途径）的信息是守恒的，并暗示大脑平行。 RGC的是输出的视网膜细胞，因而是一个重要的细胞，以研究，以了解如何在大脑中的视觉核信号光信息。在过去几十年的小鼠遗传学的进展，导致各种具体的研资局的人群是一种荧光蛋白标记，以便研资局亚型 2 3 4和电生理记录针对特定的识别荧光记者鼠标线。在这里，我们提出了一种用于记录从一个完整的，孤立的视网膜准备荧光标记的神经节细胞的光反应的方法。这个与世隔绝的视网膜准备允许来自视网膜神经节细胞树突状乔木是否完好，并保留在整个研资局的树突状乔木输入录音。这种方法适用于跨多种神经节细胞亚型，是适合各种各样的单细胞的生理技术。
