Abstract
The neuroanatomical correlates of human sexual desire, arousal, and behavior have been characterized in recent years with functional brain imaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET). Here, we briefly review the results of functional neuroimaging studies in humans, whether healthy or suffering from sexual disorders, and the current models of regional and network activation in sexual arousal. Attention is paid, in particular, to findings from both regional and network studies in the past 3 years. We also identify yet unanswered and pressing questions of interest to areas of ongoing investigations for psychiatric, scientific, and forensic disciplines.

In this study, PET scanning in women demonstrated extensive bilateral deactivation of the primary and secondary visual cortex in response to high-intensity (i.e. explicit) erotic film clips versus low-intensity erotic or neutral clips. The authors of that paper suggested their finding showed either a compensatory mechanism that facilitates increased blood supply to other brain regions involved in sexual processing or a decreased need to maintain precise visual verification of overt stimuli that are obviously sexually arousing. They further postulated emotional processing at the anterior affective system, comprising the temporal pole, amygdala, and orbitofrontal cortex, modulates the activity at the visual cortex during exposure to high-intensity visual erotic stimuli.

In this study of pornography use, significantly more activation occurred in the left putamen during viewing of pornographic materials compared to matched nonsexual cues, indicating the left putamen is also involved in sexual processing.

This study tested the hypothesis that there would be neural circuitry similarities between these subjects with compulsive sexual behavior (CSB) as those demonstrated in processing other natural and drug rewards. The experimental paradigm employed exposing sexually explicit, erotic, and non-sexual cues to participants labeled as having CSB and those without CSB. Sexual desire corresponded to the dACC-ventral striatal-amygdala functional network. Higher subjective scores of sexual desire to explicit cues were associated with greater dACC activity and enhanced functional connectivity between the dACC, ventral striatum, and amygdala, especially in the CSB participants.

This study tested two classification algorithms to identify pedophilia by fMRI in male participants with self-reported pedophilic interests versus controls. Analysis of the preference-specific brain activity in the areas known to contribute to sexual processing contributed to the high classification accuracy of the authors’ algorithms to discriminate between pedophilic and non-pedophilic subjects.
