THE SPIKE-DOME complex is a primary electric correlate of the clinical convulsive disorders. Because of its clinical importance, its striking contour, and its remarkable paroxysmal quality, the spike-dome discharge has been extensively studied in man* and, as far as is applicable, in experimental animals.1 This communication treats of the physical characteristics and the time relations of these complexes as derived from the intact scalp of man. Many complexes were recorded by relatively high-speed photography of cathode ray traces, obtained through conventional (A.C.) amplification in order to obtain sufficient resolution of the complexes to allow time measurements within 2 msec. Other complexes were recorded by low-speed direct-writing oscillographs with direct-coupled (D.C.) amplifiers.
Recordings were taken from more than 100 patients with various types of clinical epilepsy for the purposes of this investigation; these subjects ranged from 4½ to 29 years of age. The sex distribution was predominantly female. In
