- Object preference by walking fruit flies, Drosophila melanogaster, is mediated by vision and graviperceptionAlice A Robie
Department of Biology, California Institute of Technology, Pasadena, CA 91125, USA
J Exp Biol 213:2494-506. 2010..Only when both these sensory systems were impaired did flies not show the behavioral preference for the tall, steep objects...
- Vision egg: an open-source library for realtime visual stimulus generationAndrew D Straw
Bioengineering, California Institute of Technology Pasadena, CA, USA
Front Neuroinform 2:4. 2008..Together, these make the Vision Egg suitable for many psychophysical, electrophysiological, and behavioral experiments. This software is available for free download at visionegg.org...
- A "bright zone" in male hoverfly (Eristalis tenax) eyes and associated faster motion detection and increased contrast sensitivityAndrew D Straw
Discipline of Physiology, School of Molecular and Biomedical Science, The University of Adelaide, SA 5005, Australia
J Exp Biol 209:4339-54. 2006..Additionally, local neural properties vary across the visual world in a way not expected if HS cells serve purely as matched filters to measure yaw-induced visual motion...
- Multi-camera real-time three-dimensional tracking of multiple flying animalsAndrew D Straw
California Institute of Technology, Bioengineering, Mailcode 138 78, Pasadena, CA 91125, USA
J R Soc Interface 8:395-409. 2011..If combined with other techniques, such as 'virtual reality'-type computer graphics or genetic manipulation, the tracking system would offer a powerful new way to investigate the biology of flying animals...
