Abstract

The embodiment of the invention discloses a multi-encephalic region field potential recording electrode which comprises multiple single-encephalic region electrodes and single-encephalic region electrode needle holders, wherein the single-encephalic region electrodes are implanted into target encephalic regions; and the single-encephalic region electrode needle holders are used to clamp the single-encephalic region electrodes, move the multiple single-encephalic region electrodes under guidance of a stereoscopic positioning instruction respectively and implant the multiple single-encephalic region electrodes into the multiple target encephalic regions. The embodiment of the invention also discloses an implantation method for the multi-encephalic region field potential recording electrode. Through application of the electrode and the method disclosed by the invention, only local field potentials of multiple encephalic regions need to be recorded; electrode formats of multi-encephalic region field potential recording as well as corresponding electrode implantation methods can be simplified; and loads of implanted electrodes can be reduced.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a multi-brain area field potential recording electrode and an implantation method. Background technique [0002] Using multi-brain region field potential recording to analyze specific behavior-related circuit functions is a relatively common method of neural circuit analysis in the field of neuroscience - recording specific brains simultaneously on freely moving experimental animals. Regional partial field potential, test some behaviors of freely moving experimental animals while recording, and use some data signal processing methods to analyze the neural circuit function related to this specific behavior. This is very helpful for functional analysis of neural circuits. [0003] At present, there are many electrode designs that realize the field potential recording of multiple brain regions to analyze the loop function related to specific behaviors. For example, the stepping ne...
