摘要：

The aim of the present work was to study correlational interactions between individual measures of alpha-activity in the baseline electroencephalogram (maximum peak frequency, range width, depth of alpha activity desynchronization reactions, structural characteristics of alpha spindles) and measures of non-verbal intellect ("Fluency," "Originality," "Flexibility") in the Torrance test in 98 healthy male subjects. These studies provided the first demonstration that individuals with high alpha-rhythm maximum peak frequency values and prolonged alpha spindles were generally characterized by more "fluent" non-verbal intellect. In turn, high levels of originality and intellectual plasticity showed a significant association with a wider range of alpha activity and variability of alpha spindle amplitude. The highest levels of originality in solving non-verbal tasks were seen in subjects with the lowest values for individual alpha-activity peak frequencies. These measures of the alpha rhythm can be regarded as individual markers of the productivity, plasticity, and originality of non-verbal intellect. © Springer Science+Business Media, Inc. 2008.
