Fish Neurobiology


Fishes have adaptively radiated to various environments while share basic anatomical and functional features of the brain with other vertebrates including humans. The aim of our research is to reveal neural control mechanisms underlying various behaviors of fish. We believe our research in future helps us to understand not only fish but also ourselves.

1) Assoc. Prof. M. Yoshida is interested in biological basis of mind in various animals including fish. His research strategy is combining behavioral observation and recordings of brain neural activities. He aims to elucidate the mind-brain relationship using a simple vertebrate system.
