The influence of suppression on the flicker ERG

Documenta Ophthalmologica Aims and scope Submit manuscript

Summary

The evoked occipital responses on flicker stimulation of the attentively reading eye have a significantly higher amplitude than the same responses on flicker stimulation of the suppressed eye.

An effect of attention in the flicker ERG is not sufficiently demonstrated. If anything could be said about the influence of attention on the ERG it is the reverse of that on the occipital responses, i.e. attention lowers the amplitude of the ERG.

Résumé

Les réponses évoquées du cortex occipital à la stimulation lumineuse intermittente (S.L.I.) de l'oeil attentivement lisant sont d'amplitude plus haut que les mêmes réponses au S.L.I. de l'oeil supprimé.

Dans l'ERG au S.L.I. un effet de l'attention n'était pas clairement démontrable. Il y avait quelquefois une indication d'une influence de l'attention sur l'ERG en sens opposé. C'est à dire l'attention diminuait l'amplitude des réponses électro-rétinographiques.

Zusammenfassung

Die Amplituden der Reizantworten des occipitalen Cortex auf Flimmerlicht-reizung des lesenden Auges sind höher als die auf Flimmerlichtreizung des supprimierten Auges.

Ein Einfluss der Aufmerksamkeit war im ERG nicht deutlich erkennbar. Man möchte eher sagen, dass ein Einfluss in gegenseitiger Richtung zu finden war. Das heisst: die Aufmerksamkeit verkleinert die Amplituden des ERG.
