The purpose of this study is to provide a comprehensive summary of the latest developments in the experimental brain study of human sexuality, focusing on brain connectivity arousal the sexual response. Stable patterns of brain activation have been established for different phases of the sexual response, especially with regard to the wanting phase, and changes in these patterns can be linked to sexual response variations, including sexual dysfunctions. From this solid basis, connectivity studies of the human sexual response have begun to add a deeper understanding of the brain network function and structure involved.
Yet, by approaching the brain as a connected organ, the essence of brain function is captured much more accurately, increasing the likelihood of finding useful biomarkers and targets for intervention in sexual dysfunction. Recent years have seen spectacular developments in the field of human brain imaging neuroimaging that allow researchers to analyze human brain structure and function in greater detail than was ever possible.
These neuroimaging approaches have begun to be applied to the study of human sexual behavior as well. Given the prevalence of idiopathic sexual dysfunctions, this development is positive, but for sex researchers or sexologists not trained to deal with brain data, it can be difficult to get a grip on the wealth of often complex results.
In this review, we provide a comprehensive summary of the latest developments in the experimental brain study of human sexuality, with a focus on the sexual response. We will argue that brain connectivity approaches hold the highest promise to provoke breakthroughs regarding the mechanisms that govern functional brainwave dysfunctional human sexual responding.
This review almost exclusively deals with results obtained by magnetic resonance imaging MRI. Structural MRI provides information about the size, shape, and integrity of gray clusters of cell bodies, e. Diffusion tensor imaging DTI is an important structural MRI protocol that can reconstruct a three-dimensional structural map of the white matter tracts the structural connections in the brain.
Quantitative meta-analyses can combine many data sets to make more reliable inferences about morphological brain features in large populations. Functional MRI enables the detection of neural activity over time, typically related to a task, group, physiological or psychological parameter, or individual trait, resulting in functional localization activation. Functional connectivity can be measured for task-based fMRI data, but also for so-called resting state data.
The latter does not require intrusive tasks or paradigms that might keep potentially interesting subject groups e. As an example, a study using resting state study found that women had stronger functional connectivity in parts of the default mode network than men did and brainwave the menstrual cycle did not modulate this connectivity.
It was concluded that transient activating effects of gonadal hormones could not account for the sexual sexual in functional connectivity [ 7 ]. Granger causality analysis and dynamic causal models can also provide information about the direction of communication between brain areas [ 8 ]. The premise is that the central nervous system behaves as a network, or a system, that tries to achieve an optimal balance between local specialization and global sexual.
If a network has both properties, it is said to have a small-world organization, and unless there is a severe neurological condition, this usually applies to human brains [ 1011 ]. However, within a small-world organization, sexual balance might be shifted towards local specialization or global integration. Graph analysis methods can brainwave a detailed analysis of this small-world brainwave, for instance by investigating the number and location of network hubs areas that function to integrate network activity.
At least in theory, graph analysis is capable of providing the most profound insights into neural mechanisms contributing to human sexuality. Models of the human sexual response aim to provide a template to study and compare a variety of sexual responses, relatively independent of other sexuality characteristics.
This model Fig. Sexual orientation, sexual preference, and gender identity are then seen as elements determining what kind of stimuli trigger the sexual pleasure cycle. Clinically, this fits with a distinction between sexual dysfunction i. The use of a model like this facilitates comparison between neuroimaging studies that try to model different elements of the sexual response, while allowing different neuroscientific explanations and mechanisms for sexual responsiveness.
The human sexual pleasure cycle. Brain areas relevant to this sexual are depicted per phase red: increased brain activity; blue: decreased brain activity. Inhibition can be physiological pink shading or deliberate brown shading. We reviewed relevant human neuroimaging studies that were published in the period —, distinguishing studies representing the sexual response itself and factors involved in triggering a response sexual brainwave, preference, or gender identity.
Regarding the sexual response category, we distinguished studies representing wanting, liking, and inhibition phases. Studies were further categorized according to their methodology, i. This arousal categorization showed that in the domain of the sexual response, about twice as brainwave neuroimaging studies were conducted than in other domains of human sexuality, but also that the relative contribution of connectivity studies was greater in the latter.
Furthermore, within the sexual response domain, it is obvious that most of current research efforts are concentrated on the wanting phase, but that connectivity approaches are relatively more common in experiments on the liking phase of the sexual response Fig. Overview of neuroimaging studies on the sexual response from the period of to Studies were categorized by phase of the sexual response cycle investigated wanting, liking, and inhibition and by methodology activation vs.
Systematic reviews of experimental brain imaging studies of the human sexual response reveal phase-dependent patterns of brain activity Fig.
By and large, a sexual response involves very similar brain activation patterns across sexual preferences and gender groups, as long as preferred sexual stimuli are used [ 1819 ]. This pattern was refined by a recent meta-analysis, showing a largely consistent pattern across gender groups with statistically significant gender differences mainly in subcortical areas [ 20 ].
In addition, there is some indication that phase-dependency in brain response patterns over arousal course of the sexual response is less marked in women than it is in men [ 21 ]. Nevertheless, the stability of the visually evoked sexual wanting pattern was confirmed by scanning subjects on two occasions separated by 1—1.
Thus, we conclude that these patterns are robust and should be able to provide a solid basis from which sexual response-related brain connectivity can be studied. More than before, experimental designs are being developed that can avoid confounds caused by participant reaction manipulation.
Some studies use subliminal i. A novel approach involves adding cognitive loading mental rotation task to a visual sexual stimulation design to decrease the likelihood of cognitive reaction manipulation [ 24 ]. Such approaches may eliminate unwanted effects of, for instance, adherence to cultural standards on sexual responding. Neuroscientific interest in the sexual wanting domain is increasingly narrowing down on sexual desire extremes.
Increased activity to sexual cues has been demonstrated in the VS [ 2527 ] and also in the amygdala in hypersexual men [ 252728 ], which is suggestive of sexual cue sensitization. This is sometimes taken to support the addiction theory of hypersexuality [ 35 ]. Other studies, however, showed negative correlations between sexual cue-induced brain activity and hypersexual symptom severity, suggesting the involvement of different phenomena that are seemingly incompatible with addiction, like response extinction or emotional downregulation [ 2628 — 3034 ].
These data may brainwave be mutually exclusive. For instance, men with hypersexuality may be both sensitized to sexual cues or contingencies a feature of addiction and more easily lose interest or self-regulate if there is no possibility to advance the sexual response as a learned adaptation. Indeed, in a paradigm with repeated exposure of cues predicting the presentation of a pornographic picture or a monetary reward, cue-induced activity in the ACC decreased faster with repeated exposure in men with hypersexuality—but only for the sexual cues [ arousal ].
Rupp and colleagues showed that in postpartum women, amygdala responses to emotional pictures including erotic pictures was suppressed, indicating decreased sensitivity to emotional salience during the postpartum period [ 37 ].
A arousal state fMRI study suggested that antidepressant use is associated with altered functional connectivity within the sexual wanting network, especially with regard to the connectivity of the extended amygdala.
In this study, amygdala connectivity profile prior to antidepressant use reliably predicted if a subject was going to be vulnerable or resilient to antidepressant-related sexual dysfunction [ 38 ]. The question then becomes how generic and specific functions work together within this network to produce a distinct sexual interest. Although this question is far from being answered, interesting new insights have been published, mostly on the VS.
Hence, the VS might signal values for different reward types, but the neural responses for each reward type are unique and are influenced by their salience for a given person.
Indeed, relative to healthy controls, men with hypersexuality show stronger VS activity for preferred relative to non-preferred visual erotica [ 32 ]. Another area of interest in this context is the OFC, because reward subtypes are processed in different OFC subregions [ 42 ].
While primary rewards like erotic stimuli activate the OFC posteriorly, secondary rewards like money activate a more anterior portion [ 43 ].
The OFC is thus a prime candidate to further the study how the brain produces distinct sexual interest and feelings. Arousal responsiveness shows normal short-term and long-term variability. This has been studied mostly in the context of the sex steroid milieu. Contrary to the biological brainwave that fertility status drives sexual responsivity, no consistent pattern emerges from studies trying to find a relationship between visual stimulation-induced brain activity and menstrual cycle phase [ 21 ].
However, Abler and colleagues included an expectancy element arousal their study and found that, in regularly cycling women, the predicting stimulus conditioned cue activated the ACC, OFC, and parahippocampal gyrus more strongly during the luteal phase than the follicular phase. Activation in these arousal was stronger in regularly cycling women, as compared to those on oral contraceptives [ 44 ]. Testosterone is seen as the gonadal hormone most pertinent to human sexual responsiveness [ 4546 ].
Because in both 46XY and genetic women, there is less central testosterone function than in men; it was concluded that testosterone rather than genetic sex determines brain activity patterns during sexual stimulation. Brainwave, a DTI experiment studying brain structure in transgender and cisgender women and men found white matter variation that could not be accounted for by differences in testosterone function.
Trans people exhibited white matter values midway between male and female cisgender controls, despite gonadal hormone levels being either typically male or female depending on whether they were transgender women or transgender men [ 48 ]. Functional connectivity within the sexual wanting network has recently been investigated using the PPI approach, mainly in the context of perceived hypersexuality.
Men with hypersexuality and controls both show increased functional connectivity of the ACC with both the right VS and right amygdala when viewing erotica, but the strongest positive correlation with reported sexual desire was found for ACC-subcortical connectivity in hypersexuality [ 25 ]. After many repetitions of sexual stimulation, functional connectivity of the ACC with the right VS and with the bilateral hippocampus was stronger in men with hypersexuality than in controls.
Intriguingly, this increased functional connectivity within the sexual wanting network occurred in the presence of decreased ACC activity [ sexual ]. This could signify a habituation effect, but more research is required to explore this phenomenon. Another study used a sexual with cues predicting pornographic or non-erotic stimuli and found decreased functional connectivity between the VS and ventromedial PFC for men with hypersexuality compared to controls [ 28 ]. Since altered VS-prefrontal coupling has been associated with impulsivity control, substance abuse, and pathological gambling [ 49 — 51 ], these findings could be an indication of inhibition impairment in men with hypersexuality.
These studies indicate that increases in sexual behavior are marked by altered prefrontal control mechanisms. Fronto-striatal connectivity and VS connectivity hold high promise as research avenues into the fundamentals of aberrant sexual wanting. Brain imaging paradigms employing stronger and more prolonged visual sexual stimulation for example, porn moviesor tactile genital stimulation, are likely to model elements of having sex e.
Liking sex has also seen more studies sexual on brain connectivity than wanting sex has Fig. One disorder that is currently receiving particular attention is psychogenic erectile dysfunction pED. It has also been associated with persistent sexual wanting network activation superior parietal lobule specificallypossibly resulting in a failure to shift to the next phase of the sexual response cycle [ 54 sexual.
Interestingly, pED is now predominantly being studied with structural or resting state neuroimaging research paradigms, contrary to other sexual disorders that are dominated by task-based paradigms. Altered functional connectivity within and beyond sexual wanting and liking networks has been identified.
In a resting state fMRI study, pED subjects showed altered functional connectivity of the right anterior insula an area integral to interoception and emotion regulation with the dorsolateral PFC and right parietotemporal junction, compared to controls [ 55 ]. Interestingly, when subjects viewed a porn movie for the duration of the experiment instead of restingreduced functional connectivity of the right insula was also found in individuals with pED relative to healthy volunteers [ 56 ].
None of the studies discussed so far have considered whole-brain connectivity. As expected, the whole-brain connectivity profile of pED subjects and healthy subjects had a small-world organization characterized by both networks for local specialization and global integration. However, in pED, the balance was shifted towards local specialization, possibly resulting in poorer integration of network activity.
Indeed, fewer hubs integrating areas were identified in pED than in controls, indicating overall poorer global integration. Genital stimulation is the primary source of sexual pleasure liking in the brain and is a key contributor to sexual arousal [ 13 ]. Some new insights are provided by research in spina bifida patients who underwent arousal surgical reinnervation of their lifelong insensate penis to improve their sexual function.
Stimulation of the glans penis reinnervated by a groin nerve and the intact groin area contralateral to the area sexual provided the donor nerve activated the same area of the primary somatosensory cortex, as expected.
They knew that they recognized the strength and positive effects of binaural stimuli. We live in complex conditions, exposed to stressful situations on a daily basis, so this is an area that must be seriously investigated, especially.

Do this for several minutes. If you have been experiencing stress of any kind, practicing HeartMath will reduce the stress every time by at least a few points.
When you get into coherence with yourself, and smooth out your own brainwave — bringing you into more of an Alpha brainwave state — and then you touch someone else, their brainwaves automatically come into coherence. You two become entrained. This simple technique is an automatic during most sexual encounters between loving partners. When there is mutual love and appreciation coupled with adoration, the heart opens and gratitude becomes part of the love play. When you are in coherence, the alpha and theta brain waves produced bring the left and right brain hemispheres into balance and light up the entire brain.
Oxygen fills the brain and one enters into a state akin to deep blissful meditation. If a man practices bringing his awareness up the spine during sexual intercourse, instead of immediately releasing, he will begin to tap into, through practice, the ability to have more full-body orgasms similar to what a woman experiences.
These techniques are explained more in depth in tantric and Egyptian alchemical texts. Our programs are specially designed to retrain your brain from high beta levels to calming alpha levels. It is particularly useful in reducing anxiety and stress-related symptoms. Stress and tension are known to increase Beta brainwave activity in the brain.
Extremely high frequencies of Beta brainwaves 28 Hz and up are associated with fear, anxiety, excessive thinking, rapid thinking, OCD Obsessive-Compulsive Disorder , and addiction. Too much Beta brain wave activity in the right hemisphere of your brain is linked to anxiety, tension, and worry.
We also offer programs to entrain your mind to produce more Alpha and Theta brainwaves, causing a reduction in anxiety, worry and depression.
Our programs also work to balance the hemisphere of the brain. The state of consciousness that is induced is one of relaxation of inhibitions, increased awareness and heightened sensation.
