Longitudinal EEG Test-Retest Reliability in Healthy Individuals

This longitudinal dataset comprises resting-state EEG recordings from 43 healthy adults collected across four sessions over approximately two years (mean interval 7.2 months). The dataset was designed to assess test-retest reliability of quantitative EEG measures using automated preprocessing including independent component analysis and wavelet-enhanced artifact removal, enabling investigation of neural component stability and regional power dynamics.
