**3.5 Theta bandwidth changes for the subject with the lowest exam score**

One recording site shows no change in theta voltage from normal (green), five sites show no changes in theta voltage from 1 standard deviation below normal (light blue), nine sites show no changes in theta voltage from 2 standard deviations below normal (dark blue), and four sites show decreases in theta voltage from normal (green) to 1 standard deviation below normal (light blue). These findings indicate minimal changes in theta voltage for the subject with the lowest exam score. The predominant change in theta is observed at 4 of 19 sites wherein decrements from normal to 1 standard deviation below normal are found.

*qEEG brain maps for the subject with the lowest exam score. Green circles indicate the scalp recording sites where the voltages are in the normal reference range (OK = normal) for each of the standard delta (1–3 Hz), theta (4–7 Hz), alpha (8–12 Hz), and beta (15–20 Hz) EEG bandwidths. Light blue (LO = low) and dark blue (VLO = very low) circles indicate voltages 1 and 2 standard deviations below the normal reference range; red (HI = high) and yellow (VHI = very high) circles are voltages 1 and 2 standard deviations above the normal reference range, respectively. Upper panel: eyes-closed control map recorded 3 days before the first control exam covering introductory material taught in the subject's first structure–function course exam. Lower panel: eyes-closed comparison map recorded 3 days before the comparison exam covering material taught in the subject's second human structure–function course exam, 5 weeks after the control recording.*
