| Abstract(in English) | A method is proposed for obtaining the intention of completely locked-in ALS patients who cannot move any part of their bodies and have no usual communication means. The method utilizes changes in cerebral blood volume accompanied with changes in brain activity. When a patient is asked a question and the answer to it is 'yes', the patient makes his or her brain active. The change in blood volume is detected with near infrared light. The instantaneous amplitude and phase of the change are calculated using analytic signal, and the intention of 'yes' or 'no' to the question is detected using a discriminant analysis with these two quantities as variables. The rate of correct detection is 80%. |
