Oxytocin in the anterior cingulate cortex is involved in helping behaviour.

OXYTOCIN IN THE ANTERIOR CINGULATE CORTEX IS INVOLVED IN HELPING BEHAVIOUR. Behav Brain Res. 2020 Jun 27;:112790 Authors: Yamagishi A, Lee J, Sato N Abstract Empathy toward the distress of others is thought to motivate helping behaviour, in the form of voluntary action to eliminate that distress. Neuropeptide oxytocin is associated with various social cognitive abilities, including empathy and prosocial behaviour. The anterior cingulate cortex is known to be one of the brain regions underlying empathy, and one in which oxytocin receptors are expressed. However, the relationship between helping behaviour and oxytocin in the anterior cingulate cortex is still unclear. The present study investigated whether oxytocin in the anterior cingulate cortex is involved in rats' helping behaviour. In Experiment 1, we examined the influence of blockading the oxytocin receptors in the anterior cingulate cortex on helping behaviour. Impeding oxytocin in the anterior cingulate cortex delayed learning of the helping behaviour. In Experiment 2, we examined immunofluorescent colocalization of oxytocin receptors and c-fos proteins in the anterior cingulate cortex, the anterior insular cortex, and the amygdala in rats that acquired helping behaviour. We found increased c-fos expression in oxytocin receptor-containing neurons in the anterior cingulate cortex and amygdala when the rats acquired helping behaviour. In addition, the change in neural activation...
