| Outline of Final Research Achievements |
We developed an analysis method to estimate neural sources from magnetoencephalographic (MEG) data that measure activities of human brain. The method is to be applied to the data, in which the strengths of neural sources vary as the parameters of presented stimuli, such as semantic distance, but the locations do not.
The method estimates the locations from many-trial-average data and the strengths from each of few-trial-average data, to show the dependence of strength on the stimulus parameters.
We evaluated the accuracy of estimating the source strengths by a realistic simulation, and suceeded in detecting the significant dependence by applying the method to an actual linguistic MEG data.
