... of motion freezing is poorly understood. When confronted with looming stimuli, the crab Neohelice granulata freezes as the stimulus increases by 1.4 deg, which is associated with the activity level of MLG1 neurons. Looming Freezing behavior Collision avoidance Lobula neurons Escape response...

... behind was significantly biased toward the side opposite the wall. Even when the antenna on the free side without the wall was ablated, this collision avoidance was also observed, suggesting that the mechanosensory inputs from one antennae detecting an object edge would be sufficient to perceive...

Bumblebees presented all the characteristics of active vision during flight by stabilizing their head relative to the external environment and maintained close...

... bees in cluttered environments is driven by the allometry of both path sinuosity and mean flight speed. Specifically, differences in collision-avoidance behavior underlie much of the variation in flight performance across body size, with larger bees negotiating obstacles more cautiously. Thus, our...

...Lance F. Tammero; Michael H. Dickinson SUMMARY Flies rely heavily on visual feedback for several aspects of flight control. As a fly approaches an object, the image projected across its retina expands, providing the fly with visual feedback that can be used either to trigger a collision-avoidance...
