[The large somatosensory evoked responses (author's transl)]. / Les potentiels évoqués somesthésiques géants.

Giant cerebral evoked potentials have been observed in a case of brain stem tumor and in hydrocephaly. The mechanism of the amplitude augmentation has been discussed.

[Periodic discharges observed in a cerebral vascular accident (author's transl)]. / A propos d'une observation de décharges périodiques dans un accident vasculaire cérébral

The authors report a case of cerebral softening in which almost entirely unilateral periodic discharges were observed. They consisted of isolated high-voltage spiked waves predominating distinctly on the side of the lesion. The interval between spikes was always 2-3 seconds. The origin of these signs is discussed. The fact that they are not necessarily related to an infectious or metabolic disease is underlined.
