Abstract
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.
