title: [EEG mapping in partial epilepsy].
abstract: Even if mathematic treatment of EEG signals by Fast Fourier Transformation (FFT) in cases of transient epileptic discharges is still controversial, this method has been applied to 21 cases of epileptic partial seizures. Examples are shown, and compared to CT-Scan data. In 17 cases, EEG mapping identified alterations of basic activities upon a definite area. In addition, a focal peak of maximal alterations displacing itself into the limits of the whole epileptogenic area is demonstrated; it is furthermore suggested that the power spectrum keeps, especially during seizures, a peculiar ("combing") morphology, possibly specific of epileptic diseases.
