Associations between the oxytocin receptor gene (OXTR) rs53576 polymorphism and emotional processing of social and nonsocial cues: an event-related potential (ERP) study.

ABSTRACT:

Background

Oxytocin receptor (OXTR) gene polymorphisms are related to individual differences in emotional processing of social cues. However, whether OXTR polymorphisms affect emotional processing of nonsocial cues remains unclear. The present study investigated the relationship between the OXTR rs53576 polymorphism and emotional processing of social cues and nonsocial cues.

Methods

Event-related potentials were recorded from 88 male participants while images of humans and images of objects were presented as social cues and nonsocial cues, respectively.

Results

First, the results showed that GG carriers of OXTR rs53576 showed more negative N1 (50-200 ms) than AA carriers in response to images of both humans and objects. Second, GG carriers showed more negative N2 (200
