FIG. 1.
Group evoke-related potential (ERP) amplitudes (μV) at electrode F7 during the Semantic Object Retrieval Test task. Data for the retrieval condition are shown in black; data for the non-retrieval condition are shown by a dashed line. There was a significant difference (750–1000 msec) between conditions for the control group (A) but not the traumatic brain injury (TBI) group (B).
