The invention discloses a multi-specification heat preservation centrifugal pipe support for cell culture. The centrifuge pipe support comprises a centrifuge pipe cavity, a reagent bottle cavity and asupporting heat preservation part, the top of the centrifuge pipe cavity and the top of the reagent bottle cavity are open, the lower portion of the opening is of a solid side wall structure, the centrifuge pipe cavity has three specifications, and 1.5 ml, 15 ml and 50 ml of commonly-used centrifuge pipes can be placed in the centrifuge pipe cavity respectively. 500 ml of reagent bottles with cuboid bottoms can be placed in the reagent bottle cavity, the outer wall of the supporting heat preservation part is in a cuboid shape, the side wall of the combined centrifuge pipe cavity and the sidewall of the reagent bottle cavity are of an integrated structure, the middle is in a vacuum state, and four supporting legs are arranged at the bottom of the supporting heat preservation part. Centrifugal pipes of multiple specifications can be placed, reagent bottles can also be placed, the experiment space is saved, and experimenters can conveniently and orderly complete experiment operation. Inaddition, the number of placed supports is reduced, sterilization is more sufficient, and the possibility of pollution is reduced. And secondly, the transparent material enables an experimenter to well control the height of the liquid level of the reagent in the operation process.

The invention discloses a method for evaluating the cerebral cortex motor representative area of ​​the trunk muscle and its application. The method monitors the contraction degree of the trunk muscle of the subject through a biological pressure feedback instrument, and simultaneously uses the transcranial magnetic stimulation technology to stimulate the cerebral cortex motor representative area. In the area, the amplitude and latency of the motor evoked potential of the trunk muscles were recorded, and finally the data was processed by Python3.7 software to obtain a three-dimensional image of the trunk muscles in the motor representative area of ​​the cerebral cortex. The method of the invention improves the large and bulky surface electromyography equipment into an easy-to-carry, convenient and compact biological pressure feedback instrument, simplifies the experimental equipment, saves the experimental site, makes the experimental process smoother, and has wider applicability. At the same time, using the programming software to effectively process the experimental results and generate three-dimensional images makes the experimental results more clear and vivid, which is of great significance for a better understanding of the relationship between pain-brain-muscle.
