Abstract

In this study we addressed questions related to the cortical sources involved in the spatial working memory in humans. Such sources were estimated from non-invasive EEG recordings by using linear inverse procedure in a group of 9 normal healthy subjects. By using these procedures and head model, we were able to analyzed neural activation in regions of interest (ROIs) of few squared cm at the cortical level. Results showed an active participation of cortical prefrontal and parietal areas during the task phase in which an image have to be hold in the memory before an appropriate decision has to be made by the subjects.
