Abstract: An electroencephalogram analysis apparatus includes an electroencephalogram acquisition part and a comparison part. The electroencephalogram acquisition part is configured to acquire a first electroencephalogram measured at a first region on a head of a test subject and a second electroencephalogram measured at a second region positioned behind the first region on the head of the test subject. The comparison part is configured to compare a power of the first electroencephalogram in a specific frequency band with a power of the second encephalogram in the specific frequency band.
