An electrode capable of simultaneously stimulating and collecting signals and its preparation method

Abstract

The invention relates to an electrode capable of simultaneously stimulating and collecting signals and a preparation method thereof, comprising grounding wires arranged in sequence, several recording electrodes and stimulating electrodes, wherein the grounding wire is the longest, the stimulating electrode is the shortest, and several recording electrodes The length of the recording electrode close to the stimulating electrode is smaller than the length away from the stimulating electrode. Multiple recording electrodes and one stimulating electrode can stimulate one nucleus and record the signals of multiple nuclei at the same time, which can reflect the influence of electrical stimulation on the stimulated nucleus and the adjacent nuclei of the stimulated nucleus, and can simultaneously Correlation studies of multiple nuclei are performed. Since both the stimulating electrode and the recording electrode have an insulating layer, they can be left in the experimental animal body for a long time without leakage, and are 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...

[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 electrode damage, or sometimes it is necessary to conduct long-term different stimulation tests on the same animal, all of which will fail due to electrode damage.
