Significant group differences (p < .005, corrected) in theta oscillatory activity during the encoding phase. Data representing the veterans with PTSD before treatment compared to the veterans without PTSD are shown on the top row, whereas the bottom row depicts comparison of the posttreatment images of veterans with PTSD to the veterans without PTSD. Note that data from the veterans without PTSD are the same in both panels, as these participants completed only one MEG session. Before treatment, veterans with PTSD had significantly reduced theta activity (i.e., strong ERD) during several time bins in the right inferior frontal and supramarginal gyri (p < .005, corrected) compared to veterans without PTSD (top row). Following treatment, these differences in theta activity were strongly diminished and/or fully suppressed (bottom row)
