Opis

Two groups of volunteers having no eye disease were examined electro-oculo- graphically twice at ten minute intervals. One group smoked in the break, one didn't. In the non-smoking group there are a number of significant correlations between the tested parameters in the dark-period and in the light-period, which could not be found to the same degree in the smoking group. The fact that there were differences between the two groups-even though not interpretable systematicaIly-suggests, that smoking influences physiological processes in the EOG. In the second period of the test, a parallelism in the course of EOG and EEG was observed, the EEG-changes, however, are interpreted more psychologically than pharmacologicaIly.
