          As we do not know what will be useful 100 years after, we are trying to
          study what may not be useful in the present time. Our absolute mission
          is to expand the study field itself.
          Our study is not limitted in mammals, but to suspect the prototype, and
          to find generality in vertebrates, we have been comparing various neuronal
          systems in various species in comparison of other studies. However, comparison
          is not the end. Comparison finds some convergence or extraordinary system
          that only specific animal groups have, which leads us mysteries of long
          evolutionary history of vertebrates.
          Our materials are mainly in neuroendocrine peptidergic neurons because
          they are small in number, and each groups show significant distribution
          and projection (see photos above). These features even provide us good
          models for understanding subfunctionalized gene evolution because some
          ligand families have the same receptor in coomon while differential localization
          and projection characterizes their diffirent functions (subfunctionalization).
          
          We are mainly using medaka, but other vertebrates are also used depending
          on what we want to know. Such as zebrafish, goldfish, blind cave characin,
          piranha, Xenopus tropicalis/laevis, lung fish, polypterus, etc...
