Abstract :

Pigeons can be an ideal animal for the study of flying bio-robot, not only because it has sustained flying ability, loadbearing and good orienting abilities, but also because it has superiority in motion concealment, obstacle avoidance and a complete autonomous intelligent in against environment interference. In order to develop bio-robot pigeon, we studied the movement regulation function of the midbrain nuclei and other adjacent structures in pigeon. Electrical stimulation was applied in investigating the movement regulation mechanisms in pigeons under light anesthesia and freely moving conditions respectively. In the acute experiment (under light anesthesia), the pigeon was fixed to a special head adapter, after the pain reflex disappeared, then removed the scalp above the surgical field, followed by removal of the cranium with a dental drill and removal of the dura and arachnoid under stereomicroscopy. Electrical micro-stimulation (intensity=30 �¼A; pulse duration=1.0 ms; frequency=80 Hz) was applied to locate and verify the turning related brain regions. The most eligible location was marked using an anodal DC current (40 �¼A for 20 s) to deposit iron ions. After the histological localization, the brain regions related to turning behavior mainly focused in the formation reticularis medialis, tractus vestibulomesencephalicus and the nucleus vestibularis lateralis. In the chronic experiment (in freely moving conditions), microelectrodes were implanted into the brain regions determined in the acute experiment and then a brain computer interface was fixed on the pigeonâ��s skull. After the pigeon recovery, via a wireless remote-control stimulator, we successfully induced turning behavior in freely moving pigeons. Our study suggested that pigeonâ��s midbrain played an important role in modulating the pigeonâ��s turning behavior. This work will provide new knowledge in flying bio-robot research and birdsâ�� locomotion induction.
