The healthy control groups in studies with patients with PTSD, generalized social anxiety disorder and borderline personality disorder also showed increased amygdala reactivity (Bertsch et al., 2013; Koch et al., 2016a), decreased amygdala-medial PFC functional connectivity (Dodhia et al., 2014), or no effect on amygdala function (Labuschagne et al., 2010) after oxytocin. This evidence concerns the gene OXT and Borderline personality disorder.
