whole-cell recordings of light evoked excitatory synaptic currents in the retinal slice

我们采用全细胞膜片钳技术，研究突触电路，基础在视网膜的视觉信息处理。在这段视频中，我们将引导您通过光诱发电流的单个细胞在视网膜切片准备执行的全细胞记录的过程中。我们使用的动物模型水产品虎蝾螈。我们首先描述了眼睛的解剖，并显示如何安装电生理记录片。一旦切片是在录音室中，我们将演示如何执行全细胞电压钳记录。然后，我们项目切片中的视觉刺激，引起光诱发的电流反应到的光感受器。在录制过程中，我们灌注与药理代理切片，即一个8声道的灌注系统，让我们之间快速切换不同的代理。在视网膜上，视网膜片制剂被广泛用于膜片钳记录，特别是研究无长突或双极细胞，这是在整个安装准备。
