<P>PROBLEM TO BE SOLVED: To precisely analyze the state of brain functions regardless of the state of a subject. <P>SOLUTION: The brain function determining system 1 comprises a brain wave signal detecting means 2 with at least one detection part 6 disposed in contact with a scalp A for detecting brain wave signals S2, a component extracting means 3 for extracting an α wave component S3 and a non-α wave component S4 from the brain wave signals S2 detected by the brain wave signal detecting means 2, a component selecting means 4 for selecting either the α wave component S3 or the non-α wave component S4 detected by the component detecting means 3, and a brain function determining means 5 for determining the state of brain functions based on the α wave component S3 or the non-α wave component S4 selected by the component selecting means 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
