Abstract

The magnetoencephalogram (MEG) is a powerful technique for the analysis of brain activity. The magnetic signal doesn´t reduce in the brain, and we can obtain accurate information about the position of the signal source by using MEG. Our aim in this study is the analysis of the stereoscopic effect in the brain. In this report, we talk about our MEG measurement system and our pseudo stereographic pattern which is used for stimulation. We also talk about the characteristics of the MEG which is measured by projection of the stereographic pattern, and the result of the estimation of the position of a single current dipole.
