Relationships between the variation score and age. The variation scores of the five frequency bands of interests obtained from normal controls (N = 10) and dementia patients (N = 16) were plotted against age, and linear fittings were performed. Note that there are correlations between variation score and age in alpha3 frequency bands (R = −0.56; P = 0.003), when level of significance is 0.01
