Some research suggests mirror neurons may be involved in mediating responses to mediated content or pornography through empathy and vicarious mechanisms, while other literature notes that mirror-neuron areas contribute to low-level action processing rather than high-level interpretation.
This work explores the use of fNIRS neuroimaging technique using young female college students with different levels of consumption of pornography, and the activation of the prefrontal cortex (cue reactivity) when viewing a pornographic clip (cue exposure) versus a control clip. The results indicate that the viewing of the pornographic clip (vs. control clip) causes an activation of Brodmann’s area 45 of the right hemisphere (BA 45, pars triangularis) (p < 0.01). An effect also appears between the level of self-reported consumption and the activation of right BA 45: the higher the level of self-reported consumption, the greater the activation (p < 0.01). On the other hand, those participants who have never consumed pornographic material do not show activity of the right BA 45 compared to the control clip (p < 0.01) indicating a qualitative difference between non-consumers and consumers. These results are consistent with other research made in the field of addictions. It is hypothesized that the mirror neuron system may be involved, through the mechanism of empathy, which could provoke vicarious eroticism. Finally, we suggest the applications that these results may have for primary and secondary prevention programs in the field of problematic consumption of pornography.

Pornography Addiction Thanks to neuroscience, it has been possible to investigate the reasons why adolescents are more likely to develop substance use disorders than adults. The results explain how during adolescence the reward/motivation mechanisms and the limbic-emotional circuits exhibit a state of hyperactivity that fosters greater emotional reactivity and drives the search for behaviors that generate immediate reward. Furthermore, the prefrontal cortex cannot fully self-regulate, leading to increased impulsivity and risk taking ( Jordan and Andersen, 2017 ).
In this way, through reverse induction, it is possible to better understand the mechanisms that underlie the problematic consumption of pornography and even analyze the existence of possible differences or “typologies” profiles of consumers. In this sense, one of the most important differences to investigate in this field is gender differences. Inhóf et al. (2019) have recently presented strong evidence on gender differences in activation of the prefrontal cortex in internet addiction. Sometimes, this behavior ends up becoming a behavioral addiction, which may in turn increase its adverse effects.
As a consequence of the increased pornography use worldwide, there has been much focus on compulsive internet pornography as a subdomain of hypersexuality ( Carroll et al., 2008 ; Döring, 2009 ; Griffiths, 2013 ). Prevention programs manage to reach a large part of the population avoiding risks and diseases. However, there is an evident lack of neurocognitive research that makes it possible to develop better communication programs in health. Only a knowledge of the mechanisms underlying the behavior to be modified will allow the design of adequate preventive programs.
(2020) has found that the right lower frontal gyrus volume (i.e., pars triangularis) was significantly larger in both the pathological gambling and cocaine dependency versus control groups. There is an abundant bibliography that links this area with mirror neurons and empathy ( Uribe et al., 2019 ; Krautheim et al., 2019 ; Rymarczyk et al., 2019 ). Recently it has been empirically confirmed that the right hemisphere plays an important role in the interpretation of gestures and non-verbal language, especially Brodmann’s area 45 ( Inhóf et al., 2019 ; Krautheim et al., 2019 ).
In other words, the “cue exposure” would provoke a greater reaction due to the activation of a kind of “vicarious eroticism” linked to empathy rather than to the pure dopaminergic pleasure provided by brain pleasure systems. Although there is not yet enough empirical evidence, it could be thought that mirror neurons are involved in sexual behavior, especially in its empathic component. White (2019) speaks of “erotic empathy” when referring to this concept. As we have pointed out, this interpretive hypothesis would also be supported by the fact that it is the right cerebral hemisphere that shows
It’s initiation would quickly provoke a sensitization of this cortical prefrontal area, with the consequences of possible craving before discriminative erotic stimuli. In the case of secondary “prevention,” persuasion programs should focus on modifying the attitudes of the subject to eliminate or modify the consumer behavior. In the case of young women, the result of this research seems to indicate that an important motivation in the behavior of consumption of pornography may be the vicarious search for empathic links of an erotic nature that is highly driven by the mirror neuron system.
In other words, we would find two variables: the limbic pleasure system characteristic of erotic behavior and the mirror neuron system characteristic of empathic behavior involved. If these hypotheses are correct, prevention programs in young women should focus on modifying attitudes linked to the search for “erotic empathy” or “vicarious eroticism.” Said in terms of communication theory: the target’s insight indicates that the axis of communication and the strategy of preventive programs should focus on these aspects of human behavior.
Ten years ago, <i>Perspectives in Psychological Science</i> published the Mirror Neuron Forum, in which authors debated the role of mirror neurons in action understanding, speech, imitation, and autism and asked whether mirror neurons are acquired through visual-motor learning. Subsequent research on these themes has made significant advances, which should encourage further, more systematic research. For action understanding, multivoxel pattern analysis, patient studies, and brain stimulation suggest that mirror-neuron brain areas contribute to low-level processing of observed actions (e.g., distinguishing types of grip) but not to high-level action interpretation (e.g., inferring actors' intentions). In the area of speech perception, although it remains unclear whether mirror neurons play a specific, causal role in speech perception, there is compelling evidence for the involvement of the motor system in the discrimination of speech in perceptually noisy conditions. For imitation, there is strong evidence from patient, brain-stimulation, and brain-imaging studies that mirror-neuron brain areas play a causal role in copying of body movement topography. In the area of autism, studies using behavioral and neurological measures have tried and failed to find evidence supporting the "broken-mirror theory" of autism. Furthermore, research on the origin of mirror neurons has confirmed the importance of domain-general visual-motor associative learning rather than canalized visual-motor learning, or motor learning alone.
