For each, a focal ictal onset is sought, but spatial sampling issues of intracranial electrodes introduce a complexity to clinical decision making that scalp EEG does not have. This includes deciding the type of intracranial electrode and the placement locations. Depth EEG is the surgical placement of intraparenchymal electrode contacts that are along a thin, flexible, plastic tube. Grid and strip electrode contacts exist within a plastic sheet that is laid across the cerebral convexity and are discussed in Chapters 32 and 33.
