Basing their facts on the analysis of 600 patients with 12,000 epileptic attacks where discharges were simultaneously recorded from cerebral structures and the scalp, the authors attempt to define the limitations of surface recordings and the means to overcome, as much as possible, the difficulties of interpretation. These arise from physical and physiological conditions and are due, essentially, to certain characteristics of the critical discharges in the brain (limited spatial extension, brief duration, low amplitude, rapid and multidirectional propagation, and the distance of the electrodes from the surface). The most important means of resolving these difficulties is by establishing strict anatomic-electric-clinical correlations.
