Mechanisms of vision in the fruit fly

Andres-Bragado, Lucia de ; Sprecher, Simon G.

In: Current Opinion in Insect Science, 2019, vol. 36, p. 25–32

Vision is essential to maximize the efficiency of daily tasks such as feeding, avoiding predators or finding mating partners. An advantageous model is Drosophila melanogaster, since it offers tools that allow genetic and neuronal manipulation with high spatial and temporal resolution, which can be combined with behavioral, anatomical and physiological assays. Recent advances have expanded our...

Statistical modelling of navigational decisions based on intensity versus directionality in Drosophila larval phototaxis

Andres-Bragado, Lucia de ; Mazza, Christian ; Senn, Walter ; Sprecher, Simon G.

In: Scientific Reports, 2018, vol. 8, no. 1, p. 11272

Organisms use environmental cues for directed navigation. Understanding the basic logic behind navigational decisions critically depends on the complexity of the nervous system. Due to the comparably simple organization of the nervous system of the fruit fly larva, it stands as a powerful model to study decision-making processes that underlie directed navigation. We have quantitatively...
