>So we all know that pornography fucks up your brain
That's a matter of perspective, bud. And has it been proven from any perspective anyway?

>So we all know that pornography fucks up your brain, it fucks up your reward system etc
Do you have an actual source for that?

Similar to theories taken from addiction research, it has been speculated in popular science literature that pornography constitutes a prewired, naturally rewarding stimulus and that high levels of exposure result in a downregulation or habituation of the neural response in the reward network. This is assumed to elicit adaptive processes in which the brain is hijacked, becoming less responsive to pornography.11There is common agreement that the neural substrates of addiction consist of brain areas that are part of the reward network such as midbrain dopamine neurons, the striatum, and the prefrontal cortex.12,13The striatum is assumed to be involved in habit formation when drug use progresses towards compulsive behavior.14The ventral striatum in particular has been shown to be involved in cue-reactivity processing of various drugs of abuse15but also in processing of novelty.16Compromised prefrontal cortex function is among the major neurobiological modifications discussed in the research on substance abuse disorders common in humans and animals.17In studies on pharmacological addiction in humans, volumetric alterations have been shown in the striatum and prefrontal cortex.

When correlating PHs (square root) with GM segmentations, we found a significant negative association in the right striatum, namely caudate nucleus (based on the automated anatomical labeling atlas34; peak voxel:x=11,y=5,z=3;P<.001; corrected for multiple comparisons) (Figure 1A). When we used a lower threshold ofP<.005, an additional cluster in the left caudate reached significance (x=−6,y=0,z=6), showing that the effect is not clearly lateralized. We refer to the cluster as the striatum; however, for the subsequent discussion, it is noteworthy that the cluster overlaps with a reward processing literature-based probabilistic region of interest of the ventral striatum, created by means of in-house software35(predominantly monetary-incentive delay task, see eAppendix inSupplementfor details).

The GM values extracted from the cluster in the right caudate were negatively associated with the cumulative pornography consumption, computed based on the currently reported PHs and the estimate of years the pornography use had been at the same extent (r64=−0.329,P<.01); this confirmed that acute consumption and the accumulated amount over the lifetime were associated with lower GM values in the striatum. No region showed a significant positive correlation between GM volume and PHs and no significant correlations were found in WM.

The observed results of the functional-connectivity analysis are in line with the anatomical organization of the brain. The caudate nucleus, in particular its lateral aspect, receives connections from the DLPFC.49,50The prefrontal cortex has mostly been implicated in cognitive control51as well as in response inhibition, behavioral flexibility, attention, and future planning. The DLPFC, in particular, is interconnected well with other parts of the prefrontal cortex and represents many types of information, reaching from object information to response and reward outcomes as well as action strategies.51Therefore, the DLPFC is considered a key area for the integration of sensory information with behavioral intentions, rules, and rewards. This information integration is thought to result in the facilitation of the most relevant action by exerting cognitive control over motor behavior.52It has been proposed that the frontostriatal network is involved in this behavior. The afferent connections from the basal ganglia convey information regarding valence and saliency to the prefrontal cortex that houses the internal representation of goals and the means to achieve them.51,53Dysfunction of this circuitry has been related to inappropriate behavioral choices, such as drug seeking, regardless of the potential negative outcome

I feel like I have a very mild porn addiction. Now I don't even do no fap but I've been laying off the porn for a bit and I have to say just seeing a girl with a nice ass in tight jeans on the street now does so much more for me.
