Sexual offenses and the brain
2023, Handbook of Clinical NeurologyBrain Activity Unique to Orgasm in Women: An fMRI Analysis
2017, Journal of Sexual MedicineCitation Excerpt :The right angular gyrus has been implicated in states of altered perception (ie, “out-of-body experiences”27,28), which could be related to the “altered state of consciousness” at orgasm.29 This finding is consistent with previous studies showing right-side brain activation during orgasm30,31 and lateralization of brain injury effects on sexuality.32 The present findings obtained through the use of improved methodology, which decreased head-movement artifacts and corrected results for multiple comparisons, are consistent with our previous reports on brain activity at orgasm in women.14–19
The human sexual response cycle: Brain imaging evidence linking sex to other pleasures
2012, Progress in NeurobiologyFunctional neuroimaging studies of sexual arousal and orgasm in healthy men and women: A review and meta-analysis
2012, Neuroscience and Biobehavioral ReviewsCitation Excerpt :These studies (Ethofer et al., 2007; Georgiadis et al., 2009; Savic et al., 2001) suggest that gender differences in brain responses to VSS may not apply to other sensory modalities. The first neuroimaging study (Tiihonen et al., 1994) of male orgasm, based on single photon emission computed tomography (SPECT), found decreased rCBF in all cortical areas except in the right prefrontal cortex, where rCBF increased. In a first PET study of ejaculation (Holstege et al., 2003), rCBF during ejaculation was compared with rCBF recorded during manual penile stimulation performed by the volunteers’ female partners.
Neuropsychology, neuroscience, volitional impairment and sexually violent predators: A review of the literature and the law and their application to civil commitment proceedings
2012, Aggression and Violent BehaviorCitation Excerpt :Specifically, in the frontal/temporal areas, studies suggest reduced blood flow as compared to non-sex offenders (Graber, Hartmann, Coffman, Huey, & Golden, 1982; Hendricks, Fitzpatrick, Hartmann, Quaife et al., 1988; Hucker et al., 1986; Wright, Nobrega, Langevin, & Wortzman, 1990). Neuroimaging data has informed us that normal individuals experience activation of the right prefrontal cortex during sexual arousal and orgasm (Stoléru et al., 1999; Tihonen et al., 1994). Empirical evidence has demonstrated reduced blood flow in the brain and diminished skull density in sex offenders.
Opposed hemispheric specializations for human hypersexuality and orgasm?
2011, Epilepsy and BehaviorCitation Excerpt :Sexual release occurs only with orgasm and is associated with greater right hemisphere blood flow. Functional imaging studies reveal that during or just after self-induced orgasm in healthy participants, right hemisphere hyperperfusion and left hypoperfusion occur [41,42] or only left hemisphere hypoperfusion occurs [43]. The widespread asymmetries are maximal in the frontal and temporal lobes.
