Description

Multichannel nerve stimulation device Technical Field The utility model belongs to the technical field of nerve stimulation, and particularly relates to a multichannel nerve stimulation device. Background Neural stimulation technology is an important technology in modern brain science. Taking transcranial magnetic stimulation technology (TRANSCRAN I A L MAGNET I C ST imu l at ion, TMS) as an example, common transcranial magnetic therapeutic equipment is widely applied to clinical treatment, outputs a variable magnetic field through a specific coil, and induces induced current in a corresponding area of the head of an organism through the variable magnetic field, so that the regulation and control of the brain nerve or brain function network of the organism are realized. In addition, neural stimulation may be applied to the spinal site to monitor or regulate central nervous function. In order to monitor or regulate the nervous system of the brain or the spinal column and its nerve functions more precisely, a more intensive study of the nerve stimulation regulation mechanism through related animal experiments is required. In the case of rodents, behavioral tests such as maze are generally used for efficacy assessment after nerve stimulation. Therefore, a larger number of experimental animal samples (tens or even hundreds) is required to obtain higher reliability of experimental results. Because rodents grow very fast, stimulation of a large number of laboratory animal samples is required to be accomplished in a very short period of time (within a few hours). Therefore, it is important to improve the experimental efficiency by the experimental equipment.
