PROBLEM TO BE SOLVED: To provide an apparatus and method for detection of a brain neural network state in which a brain wave in the stimulus load is measured and a brain neural network state corresponding thereto is properly detected, and thereby a clue to estimate feeling corresponding thereto can be obtained.SOLUTION: An apparatus for detection of a brain neural network state is provided, and includes: a head electrode HE disposed in the head of a subject H; an amplifier 3 for obtaining an acquisition signal from each electrode and performing necessary amplification; and a signal processing device 6 for recording a post-amplification signal, removing artifacts by using a technique of eliminating noise according to need from the post-amplification signal, deriving an effective voltage after extracting a specific band component, cutting it in time series in response to a feeling generation time corresponding to the stimulus, finding a scale factor of the whole analysis by an ensemble average of the scale factor obtained by power function approximate of each power spectrum, and calculating so as to perform two dimensional plot display of the scale factor of each left and right hemisphere.SELECTED DRAWING: Figure 1 |
