Research Summary

Asuka  Takeishi(Ph.D.)

We are interested in how animals make behavioral decisions. Animals are exposed to continuously changing environmental stimuli, such as temperature, odor, light and sound. We sense and integrate these environmental cues in the nervous system in order to choose appropriate behavioral responses. We are currently investigating the mechanism of multi-sensory integration in the nervous system by analyzing behavior strategies and neural circuits of C. elegans that are exposed to multiple stimuli, especially temperature and odor. In addition to this biological approach, we incorporate mathematical and computational models to reveal the evolutionally-conserved fundamental mechanism of behavioral decision.
