Spectral electroencephalogram (EEG) analysis shows spatial coherence of a-waves over areas of the scalp. We use the correlation dimension D2 to characterize the time evolution of the cortex activity. The dimension analysis of 8 channels suggests a uniform attractor over the surface with small but consistent differences in the correlation dimension. The analysis is greatly improved by eliminating the high degree of regularity for neighbouring points in the embedding space due to oversampling.
