EXPERIMENTAL ANALYSIS OF BRAIN ACTIVITY AND BEHAVIOUR IN CHILDREN WITH “MINOR” SEIZURES1

Abstract: RESUME Ce travail démontre que les troubles bioélectriques peuvent être traités comme des variables dépendantes ou indépendantes. On a observé que des changements systématiques dans la difficulté du test pouvaient modifier de façon significative l'activité bioélectrique paroxystique de l'EEG; inversement, l'activité bioélectrique était susceptible de modifier les performances. En changeant systématiquement les paramètres de chaque test, on devrait donc arriver à réaliser un ensemble de conditions dans lesquell… Show more

“…This abnormal electrophysiologic activity manifests itself clinically in the form of multiple seizure symptoms, and when these symptoms are successfully treated, presumably the electrophysiologic dysfunction is no longer active and hence dichotic listening performance recovers. This proposed explanation is theoretically consistent with previous observations that subclinical paroxysmal activity can function as a type of "neural noise" interfering with the brain's capacity to process auditory information presented at near "channel capacity" (Hutt, 1972;Hutt & Fairweather, 1971). Further clinical precedent for this explanation can be found in a case reported by Fincham et al (1979) who observed recovery from a bilaterally dichotic listening suppression when an epileptic patient was treated with phenytoin.…”

“…Attentional impairments have been found in most of the studies addressing this aspect, in association with both infraclinical and clinical paroxysms (Tizard and Margerison, 1963;Hutt, 1972;Hutt and Fairweather, 1973;Bruhn and Parsons, 1977). The hypothesis of attentional and perceptual interference is also supported by the observation that even discharges occurring within the 10 s preceding memorandum presentation were associated with impaired stimulus recognition.…”

“…Some authors have found a correlation between the degree of impairment and the difficulty of the task. Hutt (1972) and Hutt and Fairweather (1975) have postulated that errors become more frequent as the amount of information to be processed approaches the patient's "channel capacity." In our study, this effect may be reflected in the net increase in errors observed with more complex pictures.…”
