2017), thus perhaps how abnormalities in the orbitofrontal cortex are hypothesized by some to be associated with sexual offending behaviors. In contrast, hyperactivation in the left superior parietal lobe and precentral supramarginal gyrus [44] was seen in pedophiles who had committed sexual abuse. An fmri study more specifically looking at pedophilic sex offenders compared to pedophilic nonoffenders showed significantly reduced functional connectivity among the left orbitofrontal cortex and left medial superior frontal regions, and reduced connectivity between the dorsal medial prefrontal cortex and posterior cingulate cortex in those.
In a separate sample of 203 homicide offenders, researchers also highlighted the existence of aberrations in gray matter in the orbitofrontal and ventromedial prefrontal and temporal cortex. This targeted review searched pubmed and google scholar for empirical studies using. Thus, in keeping with a fundamental role of orbitofrontal cortex, the sex offenders were impaired on tasks that require altering one's behavior in accordance with learned rules.
Specifically, pedophilic offenders demonstrated significantly reduced connectivity among the left orbitofrontal cortex and left medial superior frontal regions, and reduced connectivity between the dorsal medial prefrontal cortex and posterior cingulate cortex, compared with nonoffending pedophiles (ka ̈rgel et al
Results neuroimaging studies regarding paedophiles revealed decreased grey and white matter in brain regions implicated in sexual incitement, such as amygdala, hypothalamus and septal regions, as well as in the orbitofrontal cortex (ofc) and basal ganglia, linked to impulse inhibition and reward. As sexual assault and child sexual abuse continue to be worldwide public health concerns, research has continued to explore factors associated with sexual offending Structural and functional neuroanatomical brain differences have been examined in an effort to differentiate sexual offenders and their behavior
