ABSTRACT:
A brain-wave analysis method for analyzing a brain wave by extracting a power spectrum of the brain wave from detected brain-wave biological signals, detecting the presence or absence of peaks formed in the frequency band of each brain-wave rhythm in the power spectrum, and analyzing the brain wave based on the presence or absence of the peak spectrum; and brain-wave analysis apparatus for realizing the aforementioned method comprising a brain-wave extracting device for extracting a power spectrum with respect to a brain wave from detected brain-wave biological signals, and a peak detecting device for detecting the presence or absence of spectrum peaks formed in each brain-wave rhythm frequency band in the brain-wave power spectrum extracted by the brain-wave extracting device.
