Abstract

Stereoeletroencephalography (SEEG) has been used to define and understand the organization of epileptogenic zones of the brain. The fusion of the SEEG signals and the anatomy on a common referential is a possible method for the analysis of these signals. This work describes an experiment conducted with humanobservers in order to evaluate three different coding schemesused to visualize the magnitude of SEEG signal in anatomical context.
