Kalispera, This week we have a physiomath talk from David O'Carroll. Please come and join us in hearing about wide ranging math applications....... As always 1230 in 114 Kincaid Wed and Friday! Please come! Motion detection on the fly: adaptive properties of neurons that analyse optic flow in the insect brain. Abstract: Specialized circuits of the insect nervous system have provided insightful models for understanding motion detection by all animals. These models are, in turn, spawning promising biomimetic computer vision applications. Insects estimate velocity of moving targets reliably, yet existing models and silicon implementations of insect motion detectors provide ambiguous, inaccurate estimates of speed. Electrophysiological experiments from my laboratory suggest that adaptive feedback and other non-linear characteristics of the biological system provide an improved solution. My lectures will step through our understanding of this system, starting with the behavior of the animals and working through physiology of motion detection, to current modeling approaches.
