... by The Company of Biologists Ltd 2022 Summary: Walking blowflies apparently choose one of two objects to approach. In model simulations, a fixation scheme combined with random attention replicates this behavior without an explicit decision mechanism. Blowfly Walking behavior Attention Visual...

... straight walking phases, the retinal image flow is composed of both translational and rotational optic flow, which might affect spatial vision, as well as fixation behavior. We addressed this issue for an orientation task where walking blowflies approached a black vertical bar. The visual stimulus...

... high-speed video to analyze compensatory head movements of blowflies walking freely on differently structured substrates. We found that even a pronounced asperity of the ground structure, with bumps of almost the size of the animal, was largely compensated by the walking apparatus of the blowfly, which...

Published: 15 April 2012
...Bettina Schewe; Wolfgang Blenau; Bernd Walz SUMMARY Salivary gland cells of the blowfly Calliphora vicina have a vacuolar-type H + -ATPase (V-ATPase) that lies in their apical membrane and energizes the secretion of a KCl-rich primary saliva upon stimulation with serotonin (5-hydroxytryptamine...

...Matthew M. Parsons; Holger G. Krapp; Simon B. Laughlin SUMMARY In the blowfly Calliphora vicina , lobula plate tangential cells(LPTCs) estimate self-motion by integrating local motion information from the compound eyes. Each LPTC is sensitive to a particular (preferred) rotation of the fly's head...

...Julia Rein; Bernhard Zimmermann; Carsten Hille; Ingo Lang; Bernd Walz; Otto Baumann SUMMARY Secretion in blowfly salivary glands is induced by the neurohormone serotonin and powered by a vacuolar-type H + -ATPase (V-ATPase)located in the apical membrane of the secretory cells. We have established...

...R. Kern; J. H. van Hateren; M. Egelhaaf SUMMARY Flying blowflies shift their gaze by saccadic turns of body and head,keeping their gaze basically fixed between saccades. For the head, this results in almost pure translational optic flow between saccades, enabling visual interneurons in the fly...

...Norbert Boeddeker; Martin Egelhaaf SUMMARY During courtship, male blowflies perform aerobatic pursuits that rank among the fastest visual behaviours that can be observed in nature. The viewing strategies during pursuit behaviour of blowflies appear to be very similar to eye movements during pursuit...

...Bernhard Zimmermann; Petra Dames; Bernd Walz; Otto Baumann SUMMARY Secretory activity in blowfly salivary glands is activated by the hormone serotonin. We have investigated the distribution and activity of two cation pumps that are possibly involved with transepithelial ion transport, i.e. Na + /K...

...SIMON B. LAUGHLIN; DANIEL OSORIO In the blowfly Calliphora vicina visual signals are enhanced by amplification and antagonism as they pass from the site of phototransduction in the retina to secondorder neurones (LMCs) in the first optic neuropile, the lamina. The mechanisms responsible...
