神经科学显微镜面临哪些挑战?

显微镜是神经科学研究领域的强大工具。不过,当涉及到对神经过程进行成像以及使用不同的样品类型(例如厚神经组织或脑类器官)时,科研人员可能会面临到很多挑战。这本30页的电子书包含众多真实的案例,以讨论我们最常见到的一些挑战,同时展示了如何使用THUNDER 成像技术克服这些挑战。

为活细胞成像创造新选择

对厚实的活体样本进行成像时,主要挑战之一是获得图像质量与组织完整性之间的平衡。长时间的图像采集期间,弱信号光会导致低信号水平,导致图像对比度低以及分割和分析困难。需要通过高剂量成像或高时间分辨率成像技术加强信号强度时,这一问题更加突出。一个常见问题是:我如果快速成像、一次完成,会不会造成样本过度漂白或者细胞死亡?

精确分析宽视野荧光图像

利用荧光显微镜的特异性,即便是使用厚样品和大尺寸样品,研究人员也能够快速轻松地准确观察和分析生物学过程和结构。然而,离焦荧光会提高背景荧光,降低对比度,影响图像的精确分割。THUNDER 与Aivia 的组合可以有效解决这一问题。前者可以消除图像模糊,后者会使用人工智能技术自动分析宽视野图像,提高操作速度和精确性。下面,我们来详细了解下这一协作方法。
