Summary: Stereoelectroencephalography denotes the strategic placement of multiple depth electrodes for invasive localization of focal epilepsy in surgical patients. It differs significantly from the alternative subdural grid approach, in both conceptualization of partial epilepsy—as a 3-D distributed network, rather than as focal pathology with contiguous spread—and by the method of sampling used—which is sparse and directed rather than continuous over adjacent brain areas. The electrode implantation strategy in stereoelectroencephalography involves appreciation of these features, which are illustrated by four cases drawn from distinct electroclinical epilepsy syndromes.
