Open Access Peer-reviewed Research Article Inga Niedtfeld , Peter Kirsch, Lars Schulze, Sabine C. Herpertz, Martin Bohus, Christian Schmahl Published: March 12, 2012 https://doi.org/10.1371/journal.pone.0033293 Abstract Affective instability and self-injurious behavior are important features of Borderline Personality Disorder. Whereas affective instability may be caused by a pattern of limbic hyperreactivity paired with dysfunctional prefrontal regulation mechanisms, painful stimulation was found to reduce affective arousal at the neural level, possibly underlying the soothing effect of pain in BPD. We used psychophysiological interactions…

However, in everyday life, people must cope with emotions, which may interfere with actual task demands and may challenge functional attention allocation. Control of interfering emotions has been associated with the proper functioning of the dorsolateral prefrontal cortex (DLPFC). As DLPFC…
