Spatial distribution of non-negligible errors induced by ignoring blood vessels: RDM errors of dipolar sources. Color and size of spheres represent RDM error at source positions. Transparent gray and yellow: brain and skull blood vessels, respectively Note the non-negligibly affected sources along small vessels (e.g., black box). As draining veins, such as the sagittal sinus, were not included in our model, there are no corresponding errors. (a) Results obtained with the high-σ-model, (b) the intermediate-σ-model, and (c) the low-σ-model, all in coronal and sagittal views. Black arrows: errors due to skull foramina and intraosseous vessels.
