Characteristic Research Of Vevl Neuron Discharging On Different Direction Of The Space In Gekko Gecko

Gekko gecko has been the ideal model for the research of the bio-robot and bionic robot because of their flexible and excellent obstacle free movement ability in three-dimensional space and adaptability to the environment. We explored the response regulation of vestibular nuclei of Gekko gecko under different inclination, which pushes the understanding of neural regulation of motion and posture of Gekko gecko and provides a good enlightenment to introduce a new effective balance control mode for the gecko robot.In order to further quantificationally understand the characteristic of Vevl neuron discharging on different direction of the space in Gekko gecko, the experiment platform of balance perception for Gekko gecko was improved. Angle synchronous measuring system was added. The stent and coupling of angle sensor was designed and angle real-time display interface was designed by Matlab and Plexon. Angle synchronous measuring system successfully realized the synchronous record and display of angle signal and neural signal.Secondly, this paper further used four channel microwire array electrode to record neuronal signals in Vevl region of Gekko gecko in different spatial positions in vivo. Under the characteristic analysis and clustering analysis of Vevl Neuron Discharging on different direction of the space in Gekko gecko, we found four types of direction sensitive neurons: Roll(ipsi),Roll(contra),Pitch nose-up and Pitch nose-down. Roll(ipsi) sensitive neurons showed strong discharge in the ipsilateral 0°-120°. Roll(contra) sensitive neurons showed strong discharge in the contralateral 0°-210°. Nose-up sensitive neurons showed strong discharge in the nose-up 120°-180°, 210°, 240°. Except the nose-down 240 °, nose-down sensitive neurons showed strong discharge in other nose-down angle. The complex response pattern of vestibular neurons in the Gekko gecko may originate from a combination of different vestibular input neurons. When Gekko gecko in Roll and Pitch angles, Vevl neurons are likely to show coordination with other neurons or the dynamic balance of excitatory and inhibitory inputs through the short correlation of activities, which helps to achieve the balance control.In addition, we also explored the electric control of the experiment platform of balance perception. We used servo motor and synchronous toothed belt system to drive the rotation of the platform and Arduino mega2560 to write the program for driving the rotating platform, which preliminary realized the automatic control of the rotation of the platform.
