阐明轴突运输的机制已证明是在决定如何在长途运输中的缺陷会影响不同的神经系统疾病非常重要。在这一重要过程中的缺陷，可以对神经元的运作和发展产生不利影响。我们已经制定了夹层的协议，旨在揭露<em&gt;果蝇</em&gt;幼虫节段性的神经实时查看轴突运输。从赫德和萨克斯顿（1996）用于幼虫节段性神经immunolocalizatin公布的，我们已经适应了这种实时成像的协议。仔细解剖和适当的缓冲液条件是最大化解剖幼虫的寿命的关键。做好时，幼虫解剖生理条件下强大的囊泡运输2-3小时。我们使用的UAS - GAL4方法<sup&gt; 1</sup&gt;表达绿色荧光蛋白标记在一个单一的轴突或幼虫节段性神经轴突，通过使用不同的神经元GAL4司机的应用程序或突触囊泡。其它荧光标记的标记，例如mitochrondria（MitoTracker）或溶酶体（LysoTracker），可也适用于前观看的幼虫。 GFP -囊泡运动和粒子的运动可以被看作同时使用单独的波长。
