| Research Abstract |
We focused on the aggressive behavior between male crickets to understand how animals alter their behaviors on the demand of changing circumstances. Biogenic amines modulate motivation of many kinds of behaviors. In our behavior and pharmacological studies demonstrate that octopamine in the brain initiates aggressive motivation in the cricket. In order to get better understand, we have been developing transgenic technique to manipulate octopaminergic system in the brain. We identified biogenic amine related genes including octopamine, serotonin, dopamine and tyramine. We also developed some tools for genetic approaches. We also developed micro robot system to manipulate cricket aggressive behavior. This system makes us perform electrophysiological experiment using free moving animal with predicting the result of fight between male crickets.
