[The resting EEG in relation to neurovegetative status and spatial perception in normal young adults (author's...

The relationship between measurable EEG-parameters and an index of irritability of the autonomous system was examined. The data consisted of the resting EEGs of 488 adult students, 290 male and 198 female. Time-domain analysis was used for computerized evaluation. Females showed a significantly higher average autonomous irritability index than males. Moreover, positive correlations were found between this index and the number of occipital beta-waves; the correlation with number of alpha-waves was negative. Amplitudes tend to be correlated negatively with the index; most correlations are stronger in females than in males. In 73 proband, 35 male and 43 female,--carriers of various inherited EEG-variants and age- and sex-matched controls,--spatial perception was examined by the WU-subtest of the "Intelligenzstrukturtest" (Amthauer). Males showed significantly higher average test values than females, and in women, a significant relationship between occipital EEG and space perception was found. There appears to be a positive association between space perception and amplitude of occipital alpha- and beta-waves. On the other hand, however, carriers of the typical low-voltage EEG show very good space perception despite their low amplitudes of occipital alpha- and beta-waves.
