Greater attention capture by task-relevant emotional stimuli in mild traumatic brain injury (mTBI). Threat-related Go signals evoked greater N2-P3 amplitude than neutral signals in the mTBI group than in the control group. Parietal P3 showed a trend, and central N2 showed a significant threat-related enhancement in the mTBI group. Grand average event-related potentials (ERPs) in response to emotionally relevant Go trials are illustrated from nine electrodes that were used to form frontal (F3, Fz, F4), central (C3, Cz, C4), and parietal (P3, Pz, P4) regions of interest for statistical analysis. The bottom plots from left to right illustrate 1) average N2-P3 peak-to-peak amplitudes across all regions of interest (frontal, central, parietal); 2) central N2 peak; and 3) parietal P3 peak amplitudes for mTBI and control groups in response to emotional (NEG) and emotionally neutral (NEU) control stimuli. Error bars indicate standard error. **p<0.001.
