各种行为特征的时间特性服从幂律分布，这种特性通常被称为分形。我们最近表明，果蝇果蝇运动活动的时间模式遵循这种分布。尽管越来越多的分形图案被发现，但负责的大脑区域和神经元网络仍然未知。在这项研究中，我们表明，特异性阻断果蝇椭球体（大脑中央复合体的子结构）神经元建立的突触会导致时间模式中分形特性的丧失。我们得出结论，运动活动的时间分形模式在椭球体中受到调节。
The temporal properties of a variety of behavioral traits obey power law distributions, a property often referred to as fractal. We recently showed that the temporal pattern of locomotor activity of the fruitfly Drosophila melanogaster follows this distribution. Although an increasing number of such fractal patterns are being discovered, the brain areas and neuronal networks responsible remain unknown. In this study, we show that specifically blocking synapses established by neurons of the Drosophila ellipsoid-body, a substructure of the central complex in the brain, leads to a loss of the fractal properties in the temporal pattern. We conclude that the temporal fractal pattern of locomotor activity is regulated in the ellipsoid-body.
