Honeybee navigation: distance estimation in the third dimension.
Honeybees determine distance flown by gauging the extent to which the image of the environment moves in the eye as they fly towards their goal. Here we investigate how this visual odometer operates when a bee flies along paths that include a vertical component. By training bees to fly to a feeder along tunnels of various three-dimensional configurations, we find that the odometric signal depend...
متن کاملHoneybee navigation
How do bees estimate distance flown? It appears that they use one or both of the following cues. The first comes from measuring the amount of energy consumed when they fly to the destination by the reduction in the volume of their nectar-laden stomachs; the greater the energy consumed, the further the distance. And the second comes from measuring how much the image of the world appears to move ...
متن کاملCapturing the Third Dimension
Capturing 3-D interaction in a non-intrusive and natural way presents some obstacles. A digital camera has some appealing attributes to overcome such problems despite the fact that pictures taken by a camera have no inherent depth information. Several computer vision techniques exist to obtain 3-D information from pictures. Some of these methods tend to be expensive while others are not fully 3...
متن کاملForcing the Third Dimension
One goal of biomedical research is to reliably construct surrogate tissues for replacement therapy and to promote tissue regeneration. In this issue of Cell, Chun et al. (2006) provide insight into the molecular basis of tissue-specific differentiation. The authors show that remodeling of the extracellular matrix by the matrix metalloproteinase MT1-MMP contributes to the three-dimensional devel...
