Figure 2: Comparative spectral power head maps generated using the mean relative weighted power values at 30 scalp locations in schizophrenia (n = 28), healthy subjects (n = 25), positive symptom subgroup (n = 10), and negative symptom subgroup (n = 9): (a) delta power; (b) theta power; (c) alpha1 power; (d) alpha2 power. The maps were generated using the “griddata (v4)” method on MATLAB version 5.3.1.
