As an easily accessible part of the central nervous system, the retina has for decades been a useful model in neuroscience studies. Genetic marking of neurons has allowed detailed characterization of synaptic connections in the retina. With many methodologies available to examine function and morphology of retinal neurons, the patch clamp recording technique has been instrumental in our current understanding of vertically transmitted signals in the retina. These signals are originated from photon absorption in photoreceptors and sent to brain visual centers through spiking of retinal ganglion cells (RGCs). Despite a large body of knowledge accumulated thus far, neural diversity in vascularized mammalian retina remains unsolved and obstructs the full appreciation of retinal circuits that subserve normal vision. This is in part because most recordings were performed on retinal slices to trade lateral circuit integrity for access to more proximal retinal neurons1-3. To gain a comprehensive picture on how retina computes visual signals, it is thus desirable to record neurons in flat-mounts wherein lateral connections, large and small, may be better preserved.
When synaptic transmission from photoreceptors to bipolar cells is interrupted due to a defective metabotropic glutamate receptor 6 (mGluR6) signaling pathway in depolarizing bipolar cells4-6 or simply as the result of photoreceptor loss in degenerated retinas7-10, many RGCs exhibit oscillatory activities. These oscillations originate from multiple sources, however the one involving gap junction coupling between AII amacrine cells (AII-ACs) and depolarizing cone bipolar cells (DCBCs) has received the most attention and hence is best understood1,7,11. We have found another source, which persists under pharmacological blockade of the aforementioned AII-AC/DCBC network and drives oscillation of OFF-type SACs in Rho&#916;CTA and Nob mice with deafferentated retinas7,8,12. Here we detail our protocol of preparing retinal flat-mounts for INL neuron recording. This approach uses commercial mouse lines (Jax stock no. 006410 and 007905) to mark cholinergic retinal neurons by fluorescent protein (tdTomato) expression that is identifiable under a fluorescent microscope equipped with contrast enhancing optics. Some experimental results acquired through this approach have been previously reported4,5,7,13.

patch clamp recording of starburst amacrine cells in a flat-mount preparation of deafferentated mouse retina

哺乳動物の網膜は、複数のニューロンタイプの積層組織です。その複雑なシナプスのネットワーク内でどのように処理されるかを視覚信号を理解するために、電気生理学的記録は頻繁に個々のニューロン間の接続を研究するために使用されています。私たちは、GCL（神経節細胞層）およびマウス網膜のINL（内顆粒層）の両方で、遺伝的にマークされたニューロンのパッチクランプ記録のためのフラットマウントの準備を最適化しました。縦と横の両方の接続が前者の構成に保存されているので、フラットマウントで記録INLニューロンを研究するために大きな横方向の成分と網膜回路を可能にすること、スライスよりも好まれています。私たちは、このようなコリン作動スターバーストアマクリン細胞（SACの）として網膜におけるミラー提携ニューロンの応答を比較するには、この手順を使用しています。
