| Biological robotics has become an attractive direction in robotics researches due to its specialadvantages.Because of its excellent flying abilities and higher load-carrying,robot pigeon hasimportant practical value.To explore the function of midbrain’s subregions relative to movement, the responses of lightlyanesthetized pigeon and awake pigeon were observed and recorded through electrically stimulatingdifferent regions in pigeon midbrain.Through acute stimulation experiment(n=12), wing flapping were induced by electricalstimulation in tegmental area,along with shortness of breath, openning eyes and so on. Thedistribution areas which induce wing flapping are around the TOS, ICo nucleus of midbrain byhistological analysis. Shortness of breath, openning eyes and so on were seperately induced in somearea in midbrain.To further test and verify the function of midbrain’ subregion relative to movement,throughimplanted electrodes at the certain regions of the midbrain of awake pigeon,remote stimulationexperiments were carrid out(n=6),according to results of acute stimulation experiment.Most of theresults obtained in acute experiments could repeated in chronic experiments,maybe more severe.some new results were obtained.Effect of certain nucleus in pigeon’s movements was researched by electrolytic lesion (n=3). Noevident change were observed in control group and the second group.The third group was alwaysnodding,tilt and dull in the second day after operation.But it behaved normally in the third day afteroperation.Maybe,its central nervous system worked by compensatory mechanism.This paper established the midbrain’ subregion relative to movement preliminary by acutestimulation experiments,awake experiments and electrolytic lesion,realized artificial induction onpigeon’s locomotion and provided important information for robot pigeon. |
