Electroencephalographic detection of synesthesia

Anna Gajos, Grzegorz M. Wójcik

Abstract


In this paper the research on a person declaring synesthetic abilities will be presented.According to the current state of knowledge synesthesia activates additional cortical fields in the brainwhich can be found in the EEG. The research was conducted using an EGI-EEG system (ElectricalGeodesic Inc., Eugene, Oregon, USA) with the GeoSource software. GeoSource is a tool that implementsthe algorithms LAURA, LORETA and sLORETA. Using these algorithms for EEG analysis wecan determine where in the brain the source of activity is. The authors will try to answer the questionwhether the use of these tools can prove the occurrence of synesthesia.
