This review paper explores the neurobiological mechanisms underlying romantic and maternal love, focusing on specific brain regions and the role of the neuropeptide oxytocin. Using functional magnetic resonance imaging (fMRI), the studies examined brain activity in individuals experiencing love, revealing that romantic love activates areas such as the middle insula, anterior cingulate cortex, caudate nucleus, and putamen, which are associated with emotional processing and reward. Deactivations in regions linked to negative emotions, such as the amygdala, were also observed, suggesting that love enhances positive feelings while suppressing negative ones. Comparing romantic and maternal love, the studies found overlapping activation in brain regions abundant in oxytocin and vasopressin receptors, highlighting their importance in bonding and attachment. Oxytocin was shown to play a crucial role in enhancing social bonding, trust, and positive behaviors. It increases the recognition of emotional expressions and promotes in-group trust. Genetic variations in the oxytocin receptor gene (OXTR) were found to influence social behaviors and attachment. Behavioral interventions increasing gratitude expressions, facilitated by oxytocin, improved relationship quality and time spent together. These findings suggest that oxytocin enhances partner touch responses and visual attention to familiar faces, supporting its role in social bonding.
