EEG ANALYSIS DEVICE, EEG DEVICE, BRAIN-BRAIN INTERFACE DEVICE AND LIE-DETECTOR USING THE SAME, AND EEG ANALYSIS METHOD

摘要

PURPOSE: An EEG(Electroencephalography) analysis device and an EEG(Electroencephalography) device are provided to analyze and detect the interaction between two brains and an internal signal which is generated in the brains by connecting the EEG system connected to each subject to a hyper scan server. CONSTITUTION: In an EEG(Electroencephalography) analysis device and an EEG(Electroencephalography) device, an EGG analysis apparatus comprises a plurality of unit EEG sensors and electrode caps(110a, 110b) attached to the head of a plurality of subjects. The EEG sensor detects a brain wave from the brain of the subject in an analog type. The EGG analysis apparatus includes decoding units(120a, 120b) and a hyper scan server(130). A central processing unit calculates dynamic PDC(partial directed coherence) information which is varied according to time by using calculated EEG signal matrix.
