| Research Abstract |
Brain-computer interface(BCI)implies decoding the (human) intension from the brain activity by means of computer. We have developed BCI by analyzing electrocorticograms obtained performing either motor or verbal tasks with the cooperation of neurosurgical patients who have been temporarily implanted subdural grid electrodes. As a result, we obtained 86.6±5.8% of discriminating performance concerning motor function (three different hand movements) and 53-63% of classifying performance, which is much higher than the chance level (33%) concerning verbal intension (silent reading of three vowels).
