Multi-brain-region recording electrode as well as preparation method and implantation method thereof

Abstract

The invention discloses a multi-brain-region recording electrode as well as a preparation method and implantation method thereof, and relates to the technical field of medical equipment. The multi-brain-region recording electrode comprises a needle header and a plurality of single-brain-region electrodes connected in parallel to one another, each single-brain-region electrode has a connection endand an implantation end which are arranged oppositely, the connection ends of the plurality of single-brain-region electrodes are electrically connected with needle header, the plurality of single-brain-region electrodes are all extended in the same direction, the implantation ends of any two single-brain-region electrodes are arranged at intervals in the extension direction of the single-brain-region electrodes, and the implantation ends of the plurality of single-brain-region electrodes are used to insert into different target brain regions respectively. The multi-brain-region recording electrode provided by the invention can be simultaneously implanted into a plurality of target brain regions, is convenient and quick, saves time and labor costs, and has wide applicability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a multi-brain region recording electrode, a manufacturing method and an implantation method. Background technique [0002] Realize the synchronous recording of action potentials and local field potentials of multiple brain regions of experimental animals through brain region recording electrodes, so as to solve the problem of simultaneously performing multiple brain region electrical activities on freely moving animals under a specific behavioral paradigm The problem of functional records to analyze the relevant circuit functions under this behavior is very helpful for the analysis of neural circuit functions. [0003] At present, the single-brain-region electrodes on the market are used for signal recording of a single brain region. When performing multi-brain region signal recording, multiple single-brain region electrodes need to be implanted sequentially for differe...

AI Technical Summary

Problems solved by technology

[0003] At present, the single-brain-region electrodes on the market are used for signal recording of a single brain region. When performing multi-brain region signal recording, multiple single-brain region electrodes need to be implanted sequentially for different target brain regions. This process will consume More time and greater cost, and multiple single-brain region electrodes implanted in different positions will require a larger space, and it will not be possible when the brain volume of the implanted object is small
