Outline of Final Research Achievements

Chromatophores in squid can expand or reduce by neuronal regulation. Based on the observation, we attempt to clarify mehcanisms of the neural control of chromatophores in squid and to establish mathematical model of the regulation for future application onto transparent displays. First, we tried to establish aquarium to keep wolrd smallest squids, pygmy squids, in the lab. We then finally established the aqualium and could keep the squid alive in the lab for 1.5 months. We also succeeded to visulalized neural fibers to reach each pigmented cells from the brain. We are now trying to established mathematical model of movement of the choromatophores.
