| Outline of Final Research Achievements |
Many insects use polarization pattern of the sky for orientation and navigation. Honeybees show clear polarotaxis to a certain e-vector orientation. In this study, polarotactic behavior of the bee trained to visit an artificial feeder was analyzed. The bees caught at the feeder oriented to the e-vector they experienced during their foraging flight, indicating that they utilized polarized light information from the sky to memorize the food location and to adjust their flight direction. In addition, an extracellular recording method from polarization-sensitive neurons in the bee brain was developed, which allows us to monitor neural responses of a flying tethered bee brain in a flight simulator.
