In 1881 William R. Gowers published his seminal book “Epilepsy and Other Chronic Convulsive Disorders” [102] . Since that time a major emphasis in clinical epileptology has been determining the site of origin of the epileptic discharge. Indeed the concept that a very limited area of brain is capable of producing and maintaining the epileptic discharge forms the cornerstone of current neuro-surgery procedures that treat epilepsy by either total resection [191–208] or stereotactic destruction [191,209–221] of the offending cortical region. However, the limited success and even failure of epilepsy surgery in a number of patients has drawn attention to the possibility that the nature of epileptic generators may be much more sophisticated than initially suspected, especially in patients with long-standing medically refractory epilepsy [40,191,210,222–229] . This chapter reviews the reasons for failure of epilepsy surgery and introduces the concept of epileptic systems [191,230], i.e. networks involving many distinct regions of the brain that are active in the brains of patients with medically refractory epilepsy.
