多电极阵列的发展使研究人员能够同时记录几个到数百个甚至数千个神经元的神经元活动。光遗传学提供了一个工具箱来激发或抑制遗传定义的神经元亚群。本文详细介绍了如何将联合收割机多电极阵列(MEA)记录技术与光遗传学技术相结合,研究小白蛋白阳性中间神经元在小鼠体感皮层信号处理中的作用。我们还提供了量化视蛋白表达细胞密度的工具,并通过光遗传学刺激估计有效照明面积,从而量化光遗传学调节的神经元。
The development of multi-electrode arrays enables researchers to record neuronal activity from several to hundreds or even thousands of neurons simultaneously. Optogenetics provides the toolbox to excite or inhibit a genetically defined subpopulation of neurons. Here, we present a detailed description of how to combine multi-electrode array (MEA) recording and optogenetics to study the role of parvalbumin positive interneurons in mouse somatosensory cortical signal processing. We also provide the tools to quantify the density of opsin-expressing cells and estimate the effective illuminated area by optogenetic stimulation, resulting in a quantification of optogenetically modulated neurons.
