| Resumo: | Emotional processing is fundamental for normal socialization, interpersonal interactions, successful decision-making and overall to self-regulate behavior according to each context. Adequate emotional processing relies in the satisfactory and balance function within certain brain networks of coactivated emotional, cognitive and perceptual regions that respond and integrate the emotional information to successfully guide behavior. Magnetic resonance techniques provide a method to directly non-invasively challenge whole-brain processes underlying diverse emotional processes as well as brain functional activity during rest. The present thesis aims at identifying functional alterations within the brain networks processing emotion and connecting emotion with cognition in psychopathic individuals, along with two clinical populations showing common or opposite behavioral features such as cocaine dependence and obsessive-compulsive disorder. Overall, the five studies presented herein constitute a step forward in the characterization of how the brain responds to emotional situations and how changes in this response pattern may compromise flexible and advantageous behaviors across pathologies. |
