Description	The method of functional MRI has recently been used for the study of cerebral generators of event-related potentials (ERP), specifically, the P3 wave. Surprisingly enough, some significant discrepancies were found between current fMRI data and the results of formerly published intracranial ERP studies. Hence, the authors launched the following study in order to assess the true potential of fMRI. Using the technique of event-related fMRI and subsequent intracerebral ERP registration, the authors studied in two sessions an auditory oddball task in 8 patients with intractable epilepsy.
