Abstract

Intraoperative monitoring in epilepsy surgery includes two aspects: monitoring to aid in identifying the epileptogenic zone (focus), and the tissue that must be resected to control the seizures, and monitoring to identify the functionally important cortex, so that it can be spared in the resection. Intraoperative monitoring to aid identification of the epileptogenic zone is most often based on electrocorticogram (ECoG) recordings. Intraoperative monitoring to identify the functionally important (eloquent) cortex most often utilizes electrical stimulation mapping. These techniques are discussed in this chapter. There are also several experimental techniques for intraoperative monitoring of eloquent cortex utilizing imaging, including optical imaging of the “intrinsic” signal [1,2], infrared signal [3] or intraoperative functional magnetic resonance imaging [4] that are beyond the scope of this chapter.
