Abstract EN
Various inverse algorithms have been proposed to estimate brain electrical activities with magnetoencephalography (MEG) and electroencephalography (EEG).
To validate and compare the performances of inverse algorithms, many researchers have used artificially constructed EEG and MEG datasets.
When the artificial sources are reconstructed on the cortical surface, accuracy of the source estimates has been difficult to evaluate.
In this paper, we suggest a new measure to evaluate the reconstructed EEG/MEG cortical sources more accurately.
To validate the usefulness of the proposed method, comparison between conventional and proposed evaluation metrics was conducted using artificial cortical sources simulated under different noise conditions.
The simulation results demonstrated that only the proposed method could reflect the source space geometry regardless of the number of source peaks.
