[EEG studies in female adolescent delinquents. Quantitative and visual analysis]

Quantitative analysis and visual interpretation on spontaneous brain electrical activity were both undertaken in 41 female adolescents and 55 normal controls. Delinquent group had higher abnormal rate of electrical encephalogram (EEG) than normal group. Spectral power analysis showed that the power of fast activity was increased in central region and the power of all bands (1-30 Hz) was generally decreased in occipital region in delinquents. It indicates that synchronization of EEG in female delinquents may be weak. The results of multi-variate discrimination analysis suggest the possibility of discriminating two groups with quantitative EEG data.
