Figure 1

Distribution of relative power across the brain. Color-coded relative electroencephalography power maps for each frequency band of (A) a control subject (65 years old) and (B) an Alzheimer’s disease (AD) patient (66 years old, mild AD). Red, orange, and yellow, high relative power; blue and green, low relative power. The patient has a higher proportion of slow (delta and theta) activity, whereas the control has a higher proportion of faster (alpha) activity.
