Erotic Images Rev Up Women's Brains
Researchers Find Brainwave Activity Speeds Up in Strong Response By Jennifer Warner

June 16, 2006 -- When a woman says, "You turn me on," it may be her brain that's talking, as well as her hormones.
A new study shows looking at erotic images causes a rapid increase in women's electrical brainwave activity, effectively turning their brains on.
The brains' electrical activity fired about 20% faster when study participants viewed erotic images than when they looked at other types of images, researchers found.
"That surprised us," says researcher Andrey P. Anokhin, PhD, research assistant and professor of psychiatry at Washington University School of Medicine in St. Louis, in a news release. "We believed both pleasant and disturbing images would evoke a rapid response, but erotic scenes always elicited the strongest response."
"Usually men subjectively rate erotic material much higher than women," says Anokhin. "So, based on those data, we would expect lower responses in women, but that was not the case. Women have responses as strong as those seen in men."
Erotic Images Turn the Brain On
In the study, published in the journal Brain Research, researchers placed electrodes on the scalps of 264 women to measure brainwave activity as they viewed a series of 55 color slides. The images varied from water skiers to snarling dogs to partially-clad couples in sensual poses.
Results showed that when the women viewed erotic pictures, their brains produced electrical responses that were stronger and quicker than responses produced by the other types of images, regardless of how pleasant or disturbing the other images were.
When volunteers viewed erotic images, their electrical brainwave activity began firing within 160 milliseconds -- about 20% faster than the electrical response prompted by other images.
Researchers also found that the erotic images were processed in different brain structures than those used for other images.
The results suggest that different brain circuits may be involved in processing erotic images than in other types of everyday images, the researchers say.
In addition, Anokhin says the fact that this study showed women's brains exhibited such a quick response to erotic pictures suggests that, perhaps for evolutionary reasons, our brains are programmed to preferentially respond to erotic material.

This was obvious. But it's a whole other issue regarding what women generally prefer in choosing who to partner with. Hint: it'll be disappointing to most every guy on this board.

No, girls lie about erotic images turning them on and the lie about not caring about muscles. They all say that...until the muscley guy takes of his shirt. They should do brainwave samples on that, i'd guarantee results supportin my hypothesis.Originally Posted by SubliminalX

Not sure what you're arguing here. The article said that erotic images induce a certain measureable response in the female brain, and I agreed by saying it was "obvious." There's no disagreement here -- you confirmed my statement and also the findings in the article.Originally Posted by kwyckemynd00
Intrinsic physiological reaction and what women generally give priority to when looking for mate/partner are two separate issues.
Muscle guy who lives with his mom
Thin guy with a successful career and a clever sense of romance
But all things being equal, sure, muscle guy wins out. No argument there.

What supplements would you recommend to increase the cleverness of my sense of romance?Originally Posted by SubliminalX

I agree, a lot of girls I meet tell me muscles are not needed, but step back when a guy that's built in interested in them. It's like a lion on a steak.:bb2: Also ALL GIRLS LIKE PORN in one form or another. My girl likes the softer stuff where you dont' have the nasty visuals. Stuff like you see on cinemax, It works like a charm everytime Oh and don't forget a glass or two of wine and a lit candle. Use that little setup and you can get whatever you want:bruce1:Originally Posted by kwyckemynd00

id say the fizogen strap if you wanna add in ches to your member, but if you want to increase your sense of romances cleverness? then id say get some love dice. roll 1 touch feet with arm pit. roll 2 kiss elbow. Now thats clever.

That's interesting, because I had seen a report (I think on the news) that a trial was done comparing Men & Women, I believe testing before & after showing them erotic images, using Diagnosting Imaging (using fMRI or CT Scans) to look at hypothalamus activity. Only the men showed an increase in activity in the hypothalamus after viewing the images. Unfortunately, I do not have a link to this particular study, but found this one on PubMed (may be same one?)
Areas of brain activation in males and females during viewing of erotic film excerpts.

Various lines of evidence indicate that men generally experience greater sexual arousal (SA) to erotic stimuli than women. Yet, little is known regarding the neurobiological processes underlying such a gender difference. To investigate this issue, functional magnetic resonance imaging was used to compare the neural correlates of SA in 20 male and 20 female subjects. Brain activity was measured while male and female subjects were viewing erotic film excerpts. Results showed that the level of perceived SA was significantly higher in male than in female subjects. When compared to viewing emotionally neutral film excerpts, viewing erotic film excerpts was associated, for both genders, with bilateral blood oxygen level dependent (BOLD) signal increases in the anterior cingulate, medial prefrontal, orbitofrontal, insular, and occipitotemporal cortices, as well as in the amygdala and the ventral striatum. Only for the group of male subjects was there evidence of a significant activation of the thalamus and hypothalamus, a sexually dimorphic area of the brain known to play a pivotal role in physiological arousal and sexual behavior. When directly compared between genders, hypothalamic activation was found to be significantly greater in male subjects. Furthermore, for male subjects only, the magnitude of hypothalamic activation was positively correlated with reported levels of SA. These findings reveal the existence of similarities and dissimilarities in the way the brain of both genders responds to erotic stimuli. They further suggest that the greater SA generally experienced by men, when viewing erotica, may be related to the functional gender difference found here with respect to the hypothalamus.

Of course the article in this thread is referring to brain waves and not the hypothalamus. The activity could have been a reaction such as nervousness or embarrassment, as the above study states that there were increases in brain activity in both sexes, just not the thalamus or hypothalamus in women. But the hypothalamus seems to be an indicator of sexual arousal (and is where Testosterone signaling starts ).
Another interesting read. Ok, it's long so I just skimmed it, but it basically tests brain activity on older men (46–55) with erotic images. The older men did not show an increase in thalamus or hypothalamus activity. The hypothesis is that this may be the reason why the older men have a lesser physiological arousal in response to the erotic visual stimuli.
