圈养苍蝇和稳定的气味跟踪争取在这个舞台上是相对比较简单。这需要实践，耐心和反复试验。这个舞台上的许多部件可以进一步优化，或取代在实验的潜力产生变化。例如，较新版本的真空室要小得多，允许更多的空间低于竞技场。此外，稀土永磁材料的强度和类型可以略有不同，并可以添加额外的气味端口，以增加气味的类型和/或在实验中使用浓度。我们注意到，在设备的任何变化将需要量身定制的优化。...

a magnetic tether system to investigate visual and olfactory mediated flight control in drosophila

它已多年昆虫的视觉线索，以稳定其在风中的标题。许多动物跟踪在风中进行气味。因此，迎风视觉稳定跟踪直接气味追踪艾滋病。但嗅觉信号直接影响视觉跟踪的行为独立于风的线索呢？此外，最近的洪水在果蝇嗅觉神经生理学和神经行为遗传学研究已促使越来越技术上先进和定量的行为分析。在这里，我们修改一个磁性的系绳系统原本是为视觉实验设计配备狭窄的层流气味羽状的舞台。一只苍蝇被粘在一个小钢针，并悬浮在一个磁场，使其能够自由偏航。小直径食物的气味羽状，是直接对果蝇的头部向下，从而引发了一个饥饿的苍蝇稳定跟踪。在这里，我们集中圈养的关键机制，调整磁铁，制订的气味羽，并确认稳定的气味追踪。
