Human Brain Reacts to Transcranial Extraocular Light
Fig 2
The effect of extraocular light on emotional modulation of P300 amplitude.
(A) Grand-average ERP of the centro-parietal region. When extraocular light was OFF, emotional distractors diminished P300 amplitude compared to neutral distractors. When extraocular light was ON the valence of the distractor had no effect on the P300 amplitude. (B) Extraocular light abolished the normal emotional modulation of centro-parietal P300 amplitude. This effect was highly significant (p = .0001). Error bars: Fisher's least significant difference.
