. Aim: To identify neural predictors of target detection. Methods: EROS and EEG were simultaneously recorded from 10 participants in two session. Each trial began with a fixation cross. • On 50% of trials, a target was presented, followed by a nonoverlapping metacontrast mask; • 25% of trials were target only. • 25% of trials were mask only. Participants indicated on each trial if they detected the target. Behavioral Results: 68% detection rate. 9% False Alarm rate. Who’s controlling the brakes?
