STUDY
YAMAMOTO, Naoyuki (Prof.)
I study fish brain, including various
sensory, motor, integrative, and peptidergic
(in particular GnRH) systems. The goals of these studies are to understand
the neural substrates underlying diverse
behavior of fishes as well as the evolution
of the brain during vertebrate phylogeny.
ABECHideki (Assoc. Prof.)
I have been working on information processing of peptidergic neuronal systems in the CNS using extrahypothalamic GnRH neurons of fishes (goldfish, transgenic medaka and dwarf gourami) as models for better understanding of animal behavior.

Peripheral and central nervous mechanisms
responsible for photoreception and control
of circadian rhythms have been studied in
a variety of vertebrate animals ranging from
fish, frogs to mammals. Recent topics include
(1)genetic and endocrine basis of circadian
rhythms in fish(Medaka), (2)mechanism of
body color change in Nigrimas medaka. Genetic
basis of circadian rhythms were analyzed
in terms of related hormonal events. My scientific
interests concern how the information processing
mechanisms have evolved to adapt to the environmental
needs, and how the environment governs the
processing mechanisms in the course of evolution.
