Recording method for neck nerve signals

Abstract

The invention discloses a recording method for neck nerve signals. According to the recording method, the separated nerves sleeve in nerve recording protection rings, silk threads are sewed on the nerve recording protection rings, the silk threads are lifted as needed to draw out the nerves, and the neck nerve signals are recorded by using a neck nerve recording micro-operator; the nerve recording protection rings can be fully filled with nerve nutrient solution to maintain nerve activity, thus the nerve signals can be effectively recorded for a long time, and prevented from being dried in air; the nerve recording protection rings are marked by different colours to differentiate the different nerves. According to the recording method disclosed by the invention, by using the nerve recording protection rings, contact area can be increased and nerve injuries can be reduced, the rings can be fully filled with nerve nutrient solution to maintain nerve activity, and the nerve recording protection rings are marked by different colours, thus the different nerves can be marked and differentiated, and are not liable to confuse; by using the neck nerve recording micro-operator, the problem of signal acquisition distortion due to instable manual operations is solved and labour is saved, and the micro-operator is a five-dimensional micro-operator and used for adjusting the contact force and area of the nerves and electrodes from a plurality of angles.

Description

technical field [0001] The invention belongs to the field of nerve signal detection, in particular to a cervical nerve signal recording method. Background technique [0002] In the acute experiment of animals, the vagus nerve and sympathetic nerve in the neck of the animal are separated, and the recording of nerve signals usually requires the electrode terminal to be placed on the nerve stably. The contact with the electrode is unstable, resulting in artifacts, resulting in large signal interference, and it is not easy to record for a long time. After the cervical nerve is separated, a silk thread is usually used to pass through the nerve as a mark. When necessary, the silk thread is pulled to expose the nerve outside the body. When not recording, the nerve can be put back into the neck tissue. Usually, the method of long-term exposure of the nerve is very harmful to the nerve. Large, affecting the effective acquisition of signals, and not conducive to the later analysis. ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a neck nerve signal recording method, aiming to solve the problem that the traditional neck nerve signal recording method uses a hand-held electrode to rest on the nerve. The shaking of the hand will make the nerve and the electrode contact unstable, resulting in artifacts, resulting in The signal interference is relatively large. After the cervical nerve is separated, a silk thread is usually used to pass through the nerve. When necessary, the silk thread is pulled to expose the nerve outside the body, and the micromanipulator can be used to achieve multi-directional and multi-space movement.
