Bioelectric brain activity in boys and girls with different scaling of short time intervals

The article presents data from studies of bioelectric brain activity in boys and girls, differing in the parameters of the subjective scales of short time intervals (STI). The accuracy and deviation of the STI scaling we evaluated by the marks that subjects applied to the electroencephalogram (EEG) during testing, than we normalized the data. Based on them, we divided the subjects into clusters of under-measuring and over-measuring STI using the k-means method. Taking into account cluster membership, we characterized bioelectric brain activity. The detected differences in the EEG parameters suggest a different organization of the rhythmic activity of brain structures associated with the assessment of time in subjects under-measure and over-measure STI. Localization and severity of intercluster EEG differences differ in spatial and frequency parameters in boys and girls.
