We compared the pre-attentive processing of emotional faces in major depressive disorder (MDD) patients and matched healthy controls as indexed by the visual mismatch negativity (vMMN) elicited by emotional faces presented in upright and inverted orientations. Compared with standard neutral faces, infrequent emotional faces elicited posterior negativities between 100ms and 350ms. Early vMMN was smaller, while late vMMN was absent in the MDD group, as compared with the normal group. Face… CONTINUE READING
