A comparison of monocular visually evoked potentials in human neonates and adults
Summated visually evoked responses (VERs) to monocular and binocular light flash stimulation were obtained simultaneously from each cerebral hemisphere. A total of twenty-two newborn infants and ten young adults served as experimental subjects. Amplitude analyses and inter-hemispheric statistical co...

| description | Summated visually evoked responses (VERs) to monocular and binocular light flash stimulation were obtained simultaneously from each cerebral hemisphere. A total of twenty-two newborn infants and ten young adults served as experimental subjects.
Amplitude analyses and inter-hemispheric statistical comparisons showed a significantly greater amplitude of the contralateral VER in infants in response to monocular stimulation. This difference did not reach significance in adults although the trend was maintained. Left-right hemispheric comparisons of amplitude did not reach significance for any group.
Inter-hemispheric correlation coefficients were computed and were found to be considerably greater for the adult group.
The results were discussed in terms of their relationship to fiber counts in the ipsilateral and contralateral tracts, the respective fiber diameters and functional changes related to progressive myelinization of the developing visual system.
Several indices for assessing the degrees of functional maturity of the developing human visual system have been considered.
La sommation des réponses évoquées visuelles (REV) à des stimulations par éclairs lumineux monoculaires et binoculaires est obtenue simultanément sur chaque hémisphère cérébral.
Les analyses d'amplitude et les comparaisons interhémisphériques statistiques montrent une amplitude nettement plus grande de la REV contralatérale chez les enfants en réponse à la stimulation monoculaire. Cette différence n'est pas significative chez l'adulte, bien que la tendance persiste. Les comparaisons hémisphériques gauche-droite d'amplitude ne montrent de différence significative dans aucun groupe.
Ces résultats sont discutés en termes de leur relation avec le nombre des fibres dans les tractus ipsilatéral et contralatéral, les diamètres respectifs des fibres et les modifications fonctionnelles liées à la myélinisation progressive du système visuel en cours de développement.
Plusieurs indices permettant de mesurer les degrés de maturité fonctionnelle du système visuel humain en cours de développement ont été pris en considération. |
