In routine EEG electrodes are placed on the convessity of the emispheres following the 10-20 International System. Additional extracranial electrodes, as nasopharyngeal, ethmoidal, sphenoidal, tympanic and zygomatic, are useful in detecting epileptic abnormalities from the basal surface of the brain. In the EEG Laboratory of the Neurological Institute of Bologna sphenoidal and nasopharyngeal electrodes are now utilized in monitoring of epileptic patients with partial seizures.
