A Study Of Cerebellum In Carp Based On Motion Control

Animal robot is a straightforward application of brain-computer interface technology based on the motion control, that is, we govern the neural activity of live animals by electrical signal, turn them into animal robot whose behavior is dominated by human. Animal robot makes full use of the advantages of animal, including movement flexibility, concealment of the natural and environment adaptability. Animal robot can be used to replace mankind work under dangerous occasion and abominable environment, finish the task that the traditional technological cannot solve. Therefore it receives much attention and become one of the research hotspots at home and abroad in recent years. In this thesis, based on the background of the carp-robot motion control, the cerebellum of carp was studied as some areas of the brain are involved in the control of movement.But up to now, the research of cerebellum and other areas related to controlling movement is less. Therefore, the paper first damaged the specific locations through the method of electrical lesion, the function of regions was analysed through comparing the changes of physiological function and athletic ablity between lesion groups and control groups, the result showed that the cerebellum of carp involved in motor control. In order to explore in great depth the motion control function of the cerebellum, electrophysiological method was used to stimulate the cerebellum of anaesthetic carp that was fixed under stereotactic instrument. And the electrical stimulation of sites which induce action more times were marked by the improved heart perfusion. It is shown that electrical stimulation in different regions of the cerebellum in anesthetized carp produced bilateral and unilateral rhythmic tail movements, which more appear in the cerebellum purkinje cell layer. Purkinje neurons are large cells in the brain area called the cerebellum, which is involved in balance and motor control. Subsequently the head of carp was scaned with CT imaging techniques, providing the navigation for implanting electrodes. Then according to acute experimental results under anesthesia, we started the awake studies. The electrodes were implanted at the certain regions of carp’s cerebellum. Then we delivered electrical stimulation, and successfully elicited some basic motor patterns, such as turning right and left, forward movements, diving and surfacing et al.Our study results suggest that the carp’s cerebellum is closely related to the movement control, electrophysiological stimulation of specific regions in the carp’s cerebellum can be induced some motion behavior.
