    • Disclosed are a novel, elastic, biocompatible, micro-sized, polyimide-based multi-channel microelectrode for recording of electroencephalography (EEG) from a laboratory animal including mouse, and a method for recording of laboratory animal EEG using the microelectrode. The microelectrode may include 2 grounding electrodes and 32 recording electrodes. A connector for signal transmission easily connects the microelectrode to a signal acquiring apparatus. The total weight of the microelectrode, including the connector, does not exceed 150 mg. Laboratory animal EEG, including that of mouse, provides the advantage of monitoring the brain state of a freely moving animal following a genetic or pharmaceutical manipulation. The microelectrode can be implanted without surgery and may be detached from wires while EEG is not recorded from the laboratory animal. The microelectrode can successfully acquire broadband EEG signals from the skull of the laboratory animal and is effective in monitoring spatial and temporal pattern of brain activities of the laboratory animal.
    • 公开了一种用于从包括小鼠的实验室动物记录脑电图(EEG)的新型,弹性的,生物相容的,微尺寸的基于聚酰亚胺的多通道微电极,以及使用微电极记录实验动物脑电图的方法。 微电极可以包括2个接地电极和32个记录电极。 用于信号传输的连接器容易地将微电极连接到信号获取装置。 包括连接器的微电极的总重量不超过150mg。 包括小鼠在内的实验动物脑电图提供了在遗传或药物操作后监测自由移动的动物的脑状态的优点。 微电极可以手术植入,并且可能从电线上脱离,而EEG未从实验室动物记录。 微电极可以从实验室动物的头骨中成功获得宽带脑电信号,有效监测实验动物大脑活动的时空格局。
