Neuroimaging is an efficient tool to investigate the anatomical and functional basis of mental processes. A revision of the scientific literature regarding conditions (PTSD and major depression) connected to violence and traumatic experiences is presented, exploring the connection between these syndromes and a modified interaction between cerebral structures implicated in the control and processing of emotions. Research shows how a missing inhibition of the prefrontal cortex on the amygdala leads to hyperexcitability of the structures involved in emotional regulation, elaboration and memorization of information and with impoverishments, some of which structural, in cortical and subcortical areas at multiple levels. Neu-roimaging on the effects of psychotherapy show, in successful psychotherapeutic treatments resulting in the disappearance of the symptoms, a normalisation of the structures regarding the same limbic emotional network.
