Trauma can shape the way an individual experiences world and interacts with other people. Touch is a key component of social interactions, but surprisingly little known how trauma exposure influences processing touch. In this review, we examine possible neurobiological pathways through which influence touch lead to aversion avoidance in trauma-exposed individuals. Emerging evidence indicates that may affect sensory thresholds by modulating activity primary cortex posterior insula. Disturbances multisensory integration oxytocin reactivity combined diminished reward-related anxiolytic responses induce bias towards negative appraisal contexts. Furthermore, hippocampus deactivation during reflect dissociative state. These changes depend not only on type severity also features We hypothesise disrupted impair interactions confer elevated risk for future stress-related disorders.

This review addresses key findings on loneliness from the social, neurobiological and clinical fields. From a translational perspective, results studies in humans animals are included, with focus social interaction, mental physical illness role of oxytocin loneliness. In terms interactions, lonely individuals tend to exhibit range abnormal behaviors based dysfunctional cognitions that make it difficult for them form meaningful relationships. Neurobiologically, link has been established between hypothalamic peptide hormone oxytocin. Since interactions especially touch regulate signaling, may have an imbalance, which turn affects their health well-being. Clinically, is predictor leads increased morbidity mortality. There evidence psychopathology both cause consequence The final section this summarizes perspectives present new model complex construct
