By comparing the brains of prisoners with a diagnosis of psychopathy and other defendants who committed similar offenses but were not diagnosed with the disease, researchers at the University of Wisconsin-Madison and New Mexico, USA,found important differences:
Psychopaths show a reduction of the connections between theventromedial prefrontal cortex (wmPFC), part of the brain responsible for sentiments such as empathy and guilt, and the amygdala involved in fear and anxiety.
To perform the analysis took two images of the brain. Magnetic resonance diffusion tensor showed a reduction of the structural integrity of white matter fibers that connect the two areas (thevmPFC and amygdala), the functional magnetic resonance imaging (fMRI) showed, on the other hand, lower coordinated activity between the vmPFC and the amygdala.
That is, the combination of structural and functional alterationsprovide compelling evidence that the dysfunction observed in this important socio-emotional circuit, is a feature of psychopathiccriminals, "said psychology professor Joseph Newman, of the Universidad de Wisconsin, participant in the study.
The results of the study, carried out in a medium security prison inWisconsin, may help explain the cruel and impulsive anti-socialbehavior exhibited by some psychopaths.
it's very interesting. i think, there are some people that are going to need this study. to know if they have this behavior. Oops!
ResponderEliminarthe serial killers are usually psychopaths because they're not able to feel any culpability,shame or pain of their actions.
ResponderEliminarit is good to take the trouble to investigate the behavior of criminals, as this can decipher it act that way and possibly to avoid these behaviors!
ResponderEliminarvery interesting, as psychopaths Sinetar not any guilt or remorse in his actions.
