Electrode capable of carrying out simulation and collecting signal simultaneously and preparation method thereof

Abstract

The invention relates to an electrode capable of carrying out simulation and collecting a signal simultaneously and a preparation method thereof. The electrode comprises a ground wire, a plurality of recording electrodes and a simulating electrode, wherein the ground wire, the recording electrodes and the simulating electrode are successively arranged. The ground wire is the longest; the simulating electrode is the shortest; and the recording electrode approaching the simulating electrode is shorter than those far away from the simulating electrode among the multiple recording electrodes. The multiple recording electrodes and one simulating electrode can simulate one nuclear group and signals of multiple nuclear groups can be recorded, so that the influences on the simulated nuclear group and the nuclear group adjacent to the simulated nuclear group by electric simulation can be reflected and correlated researches on multiple nuclear groups can be carried out simultaneously. Because the simulating electrode and the recording electrode contain insulating layers, the electrode can be placed in a tested animal body for long time without an electricity leakage phenomenon, so that the electrode is safe and durable.

Description

technical field

[0001] The invention specifically relates to an electrode capable of simultaneously stimulating and collecting signals and a preparation method thereof. Background technique

[0002] The electrodes in the prior art are generally separated from the stimulating electrodes and the electrodes for collecting signals, and most of them use glass microelectrodes to collect signals. In this way, in addition to the inconvenience of the experiment, only the anesthesia signals of animals can be collected. In addition, the existing electrodes Generally, only the signal of one nucleus can be collected and signals of multiple nuclei cannot be collected at the same time. When one nucleus is stimulated, the reaction of the stimulated nucleus and its adjacent nuclei cannot be accurately reflected. In addition, most Electrodes cannot be left in the body for long-term application. For some stimulation factors that require long-term observation, they cannot be verified due to ele...
