Age-Related Changes in EEG Formation during Transcranial Direct Current Stimulation

The EEG power spectra in the main bands (4 to 20 Hz) were compared during transcranial direct current stimulation (tDCS) treatment in children with mental development disorders of perinatal origin. In resting state with the eyes closed, a shift in the average frequency of α activity in the parieto-o...

Description
Summary:The EEG power spectra in the main bands (4 to 20 Hz) were compared during transcranial direct current stimulation (tDCS) treatment in children with mental development disorders of perinatal origin. In resting state with the eyes closed, a shift in the average frequency of α activity in the parieto-occipital area (from 9 to 10 Hz) and an increase in the spectral power stronger in the right hemisphere were observed. With the eyes open and closed, a decrease in the β range power spectrum in the right posterior temporal cortex was observed in children undergoing tDCS treatment. The power spectra of θ activity with a frequency of 4–5 Hz in the left posterior-temporal area with the eyes open showed negative correlation with age.
