Compartmentalization and axon guidance in the Drosophila brain
… two distinct compartments, the lamina and lobula, and find that the secreted ligand Slit is present in the lamina, while the Robo receptors (Robo, Robo2 and Robo3) are expressed on lobula neurons. I examined the function of theses proteins by identifying a tissue-specific allele of slit and …

Activity Dependent Trans-synaptic Tracing Of Neural Circuits In Drosophila
… the inner photoreceptors in the retina to the lobula complex in the Drosophila visual system. Elucidation of neural circuits and the mechanisms involved in translating the circuitry into a meaningful behavioral response with Tango-trace involves labeling of neurons in an activity-dependent …

Signal transformation at the input and output of the Drosophila visual system
… at the output end, in the third optic neuropil, lobula. Visual projection neurons project from the lobula to the central brain, and have been proposed to carry behaviourally relevant visual features to higher brain regions. It was recently shown that optogenetic activation of individual visual …

Using new tools to study the neural mechanisms of sensation: Auditory processing in locusts and translational motion vision in flies
… lab and I showed that this cell-type – named Lobula Plate Columnar 1 (LPC1) – is required for the stopping behavior of walking flies caused by back-to-front translation motion but is not involved in the rotational optomotor response. Using calcium imaging, I found that LPC1 was selectively …

Xhosa Single Mothers: Reasons for Remaining Single
… their partners which limits their ability to pay lobula, distrust of men, apartheid, and urbanization, are all explored in this study as reasons for these mothers remaining single.</p>

The Localization of GABA-Like Immunoreactivity in the Optic Lobe Neuropils and Optic Tracts of the Cockroach Leucophaea Maderae
… neuropils of the optic lobes (lamina, medulla, lobula) and in the optic tract of the cockroach L. maderae. The localization of GABA-like immunoreactivity in the optic lobes and tract of L. maderae is consistent with findings in other invertebrates, including other species of cockroaches.

Genetic Intervention in Sensory Systems of a Fly
… vertikale Bewegung sensitiven VS Zellen in der Lobula Platte erwiesen sich als nicht notwendig für die Verhaltensreaktionen auf vertikale Bewegungsreize. Daraus folgt auch, daß in der Strukturmutante optomotor blind das Fehlen der VS Zellen nicht ursächlich für die stark eingeschränkten …

Collision avoidance behaviour in a pair of flying locusts (Locusta migratoria L.)
… pathway underlying this behaviour are the lobula giant movement detector (LGMD) and its postsynaptic component, the descending contralateral movement detector (DCMD). Previous studies have suggested that the LGMD/DCMD pathway allows each locust within a dense swarm to remain sensitive to …
