Abstract

The invention discloses an in-vivo multichannel electroencephalogram signal recording device. The device comprises an electrode installer, a plurality of micro-drivers and a plurality of connectors, the micro-drivers are used for being implanted into a designated area of an animal brain and arranged in the electrode installer, and the connectors are installed in the electrode installer and connected with the animal brain through microwire electrodes. The electrode installer comprises a main body, a cover body, a base and a connecting sleeve, the base is used for being implanted into the brain of an animal, the main body is arranged on the base and provided with an observation window, a microwire electrode and a plurality of micro-drivers can be observed through the observation window, the micro-drivers can be adjusted through the observation window, the connecting sleeve is installed on the main body and used for installing the plurality of connectors, and the cover body is installed above the observation window and is matched with the main body to limit the connecting sleeve between the main body and the cover body. The in-vivo multichannel electroencephalogram signal recording device of the invention can record single peak and local field potential from different brain areas in the brain of an animal at the same time.

Description

technical field [0001] The invention relates to the field of electroencephalogram signal detection, in particular to an in vivo multi-channel electroencephalogram signal recording device. Background technique [0002] Metallic recording electrodes have been widely used to record single neuronal spike activity (Spike) and local field potential (LFP) in brain regions. However, establishing an easily assembled large-scale recording device in multiple brain regions for long-term stable monitoring of neural activity remains a daunting task. [0003] In neuroscience, monitoring and studying the electrical activity of the brain has greatly advanced our understanding of the electrical properties of individual neurons and macroscopic neural connections. While some techniques and tools (such as voltage-indicating probes or calcium imaging) are already available for the study of the activity properties of individual neurons, techniques such as single neuron, multiple neuron, and local...
