FIG. 4.

This figure presents the regions that exhibited a significant validity×SOA interaction when mild traumatic brain injury (mTBI) and healthy controls (HC) were collapsed. The magnitudes of z-scores are represented by either red or yellow coloring. Locations of the sagittal (X) and axial (Z) slices are given according to the Talairach atlas (L, left; R, right). Percent signal change (PSC) values for the regions implicated in the interaction are presented for valid (red bars) and invalid (blue bars) trials at 200, 400, and 700 msec SOA. The areas included the bilateral pre-supplementary/supplementary motor area (B_P-SMA/SMA), the near left frontal eye fields (L_FEF), and the left inferior parietal lobe (L_IPL). Error bars correspond to the standard error of the mean (SOA, stimulus onset asynchrony).
