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

我々は、シナプス回路が網膜の基礎となる視覚情報の処理を研究するためにホールセルパッチクランプ法を使用してください。このビデオでは、我々は、網膜のスライス標本における個々のセルの光誘発電流の全細胞記録を実行するプロセスをガイドします。我々は、動物モデルとして水生トラフサンショウウオを使用してください。我々は目の解剖を記述することで開始し、スライスを電気生理学的記録のためにマウントする方法を示します。スライスが録音室に配置されると、我々は、ホールセル電圧クランプ記録を実行する方法を示します。我々は、その後、光誘発電流応答を引き出すためにスライスに光受容体の上に視覚刺激を投影。録音中に我々は、8チャンネルの灌流システムは、私たちはすぐに別のエージェントを切り替えることができることにより、薬理学的薬剤とスライスを灌流。網膜スライス標本は広く、特にホールマウントの準備にはアクセスできないアマクリンまたは双​​極細胞を、研究するために、網膜でのパッチクランプ記録のために使用されます。
