[Very early deflections of the visual evoked response (author's transl)].
The authors confirm the presence of very early deflection (before the 20th msec. after the flash). They probably have their origin under the cortex. The curves showing the attenuation of the spontaneous activity during the summation and those illustrating the evolution of the variancy of the early portions of the VER are comparable. By contrast, the stability of the curves related to later fractions state problems about the often pretented independancy of spontaneous and evoked activities.
