**3.6 Beta bandwidth changes for the subject with the lowest exam score**

A total of 16 recording sites show no change in beta voltage from 1 standard deviation below normal (light blue), one site shows no change in beta voltage from 2 standard deviations below normal (dark blue), one site shows a decrease in beta voltage from normal (green) to 1 standard deviation below normal (light blue), and one site shows an increase in beta voltage from 2 standard deviations below normal to 1 standard deviation below normal. These findings also indicate minimal changes in beta voltage for the subject with the lowest exam score. The predominant change in beta is observed at 16 of 19 sites wherein no changes from 1 standard deviation below normal are found.
