Abstract

The invention provides a rat cerebral electrical stimulation device and electrode fixing bases thereof. The electrical stimulation device comprises an electric simulator, two electrode fixing bases, and an electrode wire capable of electrically connecting the electric simulator and the electrode fixing bases, wherein each electrode fixing base comprises an insulated fixing section, an electrode inserting section, a conductive contact section and a bolt; two or more bolt limiting holes are formed in the insulated fixing section in a center symmetry manner; the electrode inserting section is fixedly arranged at the center position of the upper end surface of the fixing section; a conductive electrode inserting hole is formed in the center of the inserting section; the conductive contact section is arranged at the center position on the lower end surface of the fixing section; the upper end of the contact section penetrates through the fixing section and is connected with the electrode inserting hole; the lower end of the contact section is arranged to contact a cerebral dura mater of a rat after passing through the rat brain; and the bolt is matched with the bolt limiting hole and is used for fastening the fixing section on a rat skull. According to the rat cerebral electrical stimulation device, a simulation electrode can be stably arranged on the rat skull in a plug and play manner, and the technical problems that an electrode in the prior art easily falls off and the electrode inserting depth is difficult to control are solved.

Description

technical field [0001] The invention relates to an electric stimulation technology of an experimental animal model, in particular to a rat brain electric stimulation device and an electrode fixing seat thereof. Background technique [0002] Rats, belonging to the mammalian order Rodentia Muridae, have fast reproductive speed and strong adaptability to external environments. They are commonly used experimental animal models in biomedicine and occupy an important position in biomedical research. [0003] Migraine is a neurological disease with high incidence in humans. Due to limited experimental models and experimental methods, researchers have restricted their research on its pathogenesis and therapeutic effect. At present, there is still a lack of recognized and reliable experimental methods and experimental devices for the establishment of experimental models of migraine rats in the world. However, it is generally recognized by the academic community that electrical stimul...
