Abstract
Disclosed is a brain wave leading apparatus which can achieve a high brain wave leading efficiency when a human brain wave frequency is led to a desired frequency band. This brain wave leading apparatus comprises a brain wave sensor for detecting the brain wave of a person to be tested (subject) during brain wave leading, and a control unit for renewing a leading center frequency for leading the brain wave frequency therewith. The brain wave frequency of the subject is measured even during brain wave leading, and based on a weighted mean frequency f' detected in a predetermined interval, a leading center frequency F in a subsequent interval is determined. The leading of the brain wave frequency is continued with the leading center frequency F supplied from the control unit. Even if the weighted mean frequency of the subject during leading varies, therefore, the leading center frequency follows up that change, so that brain wave leading will be executed in a short period of time.
