The SEEG is an invasive diagnostic technique developed in France in the 1960s by Bancaud and Talairach in the Sainte-Anne hospital. It involves the implantation of multiple microelectrodes using stereotactic technique. Designing a correct implantation scheme requires many years of practice and experience. Its goal is the evaluation of an anatomo-electro-clinical correlate in the generation and propagation of seizures. Therefore, the analysis of these records allows us to know the spatio-temporal dynamics of epileptic seizures related to semiology with a high degree of anatomical precision.
