Whole-cell recordings from pyramidal neurons in turtle visual cortex.

Schematic diagram of an isolated piece of turtle dorsal cortex (left panel) with the ventricular side up and containing pyramidal neurons (blue) and interneurons (grey). A whole-cell recording of the pyramidal neuron membrane potential in response to current injection (right panel) is obtained with a patch electrode (grey triangle) that is positioned at the pyramidal neuron soma under visual guidance with DIC optics.左侧面板为一块分离的龟背侧大脑皮层示意图，其脑室侧（ventricular side）朝上，内含锥体神经元（pyramidal neurons，蓝色）与中间神经元（interneurons，灰色）。右侧面板为全细胞记录（whole-cell recording）结果：借助膜片钳电极（patch electrode，灰色三角），在微分干涉差光学（DIC optics）的可视化引导下将电极定位至锥体神经元胞体（soma），从而记录得到电流注入刺激下的锥体神经元膜电位响应。
