Research Summary

In order to interact successfully with the environment, animals must deduce their surroundings based on sensory information. The visual system plays a particularly critical role in such interactions with the environment. "Why can we see?" This question is fundamental for a thorough understanding of vision-dependent animals, including human beings. In order to better understand the sensory systems of animals, we are researching the visual system by using computer and mathematical modeling. Please see http://www.nibb.ac.jp/neurophys/ for details.

PhD Program

This laboratory is currently recruiting graduate students.
