果蝇被广泛用作模型系统来研究神经变性。这个协议描述由退化,如由大脑液泡形成确定的,可量化的方法。它也最大限度地减少的效果因的实验程序由处理和切片对照和实验苍蝇,因为一个样本。

该程序的总体目标是量化果蝇大脑中的神经退行性变,由多种因素引起,包括年龄、基因改造或环境影响,而无需进行特异性染色。该方法在分析神经退行性疾病领域的关键问题时非常有用。例如,哪些基因或环境因素导致或促成了这些疾病?

这种方法的主要优点是它避免或最大限度地减少了系统误差,因为对照果蝇和实验果蝇被视为一个样品。通常,刚接触这种方法的人可能会很困难,因为需要练习才能确保大脑的正确区域位于滑轨上并防止切割过程中可能发生的损伤。首先,首先使用镊子将受试者的苍蝇的脖子穿入项圈。
