Key findings

  • Mapping aims to identify and characterise seizure-generating zones
  • These zones vary in number, extent and distance from the recording electrodes
  • Maps are most useful when combined with the rest of the clinical picture

A review of how EEG maps are used when planning epilepsy surgery, covering aims, difficulties and the techniques available at the time. The goal of mapping is to pinpoint and describe the brain zones that generate seizures, which may be single or multiple, focal or spread out, and close to or far from the electrodes. Interpreted alongside other clinical information, the recorded electrical fields can often localise seizure foci more precisely.
