Pädophilie - Hirnareale und neurologische Veränderungen
Pädophilie"Regions showing differential activations during the erotic condition comprised the hypothalamus, the periaqueductal gray, and dorsolateral prefrontal cortex, the latter correlating with a clinical measure. Alterations of emotional processing concerned the amygdala-hippocampus and dorsomedial prefrontal cortex." Q"Compared to the homosexual and heterosexual control subjects, pedophiles showed decreased gray matter volume in the ventral striatum (also extending into the nucl. accumbens), the orbitofrontal cortex and the cerebellum." Q "As deduced from the network model, all four patients exhibited pronounced and circumscribed deficits in cognitive domains mediated by striato-thalamically controlled areas of the frontal cortex. All patients were especially impaired in neuropsychological functions associated with the prefrontal and motor processing loops (e.g., response inhibition, working memory and cognitive flexibility), with a performance level located up to five standard deviations below the normative data." Q "Subtle defects of the right amygdala and closely related structures might be implicated in the pathogenesis of pedophilia and might possibly reflect developmental disturbances or environmental insults at critical periods."

| Orbitofrontaler Kortex | "(...) responses to visual sexual stimulation were found in the orbitofrontal cortex in healthy heterosexual males, but not in paedophiles, in whom abnormal activity in the dorsolateral prefrontal cortex was observed." Q | ||
| Dorsolateraler PFC |
"Regions showing differential activations during the erotic condition comprised the
hypothalamus, the periaqueductal gray, and dorsolateral prefrontal cortex, the latter
correlating with a clinical measure."
Q " (...) in paedophiles (...) abnormal activity in the dorsolateral prefrontal cortex was observed." Q |
||
| Amygdala | "Pedophilic perpetrators showed a significant decrease of right amygdalar volume, compared with healthy controls (P = .001). We observed reduced gray matter in the right amygdala, hypothalamus (bilaterally), septal regions, substantia innominata, and bed nucleus of the striae terminalis." Q | ||
| Striatum | "(...) during presentation of the respective sexual stimuli, the thalamus, globus pallidus and striatum, which correspond to the key areas of the brain involved in sexual arousal and behaviour, showed significant activation in pedophiles, but not in control subjects." Q | ||
| Globus Pallidus | "(...) during presentation of the respective sexual stimuli, the thalamus, globus pallidus and striatum, which correspond to the key areas of the brain involved in sexual arousal and behaviour, showed significant activation in pedophiles, but not in control subjects." Q | ||
| Thalamus | "(...) during presentation of the respective sexual stimuli, the thalamus, globus pallidus and striatum, which correspond to the key areas of the brain involved in sexual arousal and behaviour, showed significant activation in pedophiles, but not in control subjects." Q | ||
| Hypothalamus | "Regions showing differential activations during the erotic condition comprised the hypothalamus, the periaqueductal gray, and dorsolateral prefrontal cortex, the latter correlating with a clinical measure." Q | ||
| Periaquäduktales Grau | "Regions showing differential activations during the erotic condition comprised the hypothalamus, the periaqueductal gray, and dorsolateral prefrontal cortex, the latter correlating with a clinical measure." Q | ||
