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.
Claims9
An electroencephalogram analysis apparatus, comprising:
- circuitry configured to:
- obtain a first electroencephalogram at a first region on a head of a test subject and a second electroencephalogram at a second region that is behind the first region on the head of the test subject;
- determine the test subject is in a sleeping state based on the obtained first electroencephalogram and the obtained second electroencephalogram;
- compare a first power of the obtained first electroencephalogram in a specific frequency band with a second power of the obtained second electroencephalogram in the specific frequency band, wherein the comparison is based on the determination the test subject is in the sleeping state;
- and
- output, based on a result of the comparison, an estimation result that indicates a state of the test subject is at least one of normal, depression, schizophrenia, or bipolar disorder.
