Knee Orgasms, Nose Orgasms, oh my!

Wired News is always one to cater to a large variety of interesting topics, but one article I recently ran across that Google News Alerts delivered to my email is a wired news special on fmri studies and orgasms.

Of the things discussed were the real existance of so-called knee orgasms, nose orgasms, and a number of other orgasms. What the article is getting at is the very idea of what an orgasm is may be changing based on these studies.

Komisaruk: Orgasms have been described as being elicitable from any part of the body — the mouth, the nipples, the anus, the hand. It leads us to think that there is a general orgasmic principle of building up excitation from different parts of the body leading to a climax and a resolution — not necessarily ending in ejaculation, but a feeling of an orgasmic experience.

The article also discusses the surprising finding that some women who had no feeling below the waist were even able to achieve genital orgasm through the vagus nerve.

Link Between Headaches (Migraines) and Depression

A study links migraine headaches, especially if accompanied with nausea or stomach/back pain, to major depressive disorder.

About 10 percent of the population suffers from migraines. Women are more than twice as likely than men to have them. For 4 percent of the U.S. population, the headaches are chronic; that is, they occur more than 15 times a month.The study found that women who had disabling chronic migraines – accompanied by other pain – were 32 times more likely to suffer from major depression than women with infrequent, nondisabling migraines without other severe pain symptoms.

Even women with headaches less than 15 times a month have a tenfold greater risk of major depressive disorder if they rated their headaches disabling and experienced severe pain of other types. (Source: Toledoblade)

I find it interesting to note when different conditions seem (and/or proven to be via study) to be connected. Such as that of diabetes, and depression.

Scientists Make Fruit Flies Bisexual

“When we mutate the protein, we get less ambient extracellular glutamate, more glutamate receptors, and so a stronger transfer of messages at synapses,” Featherstone said.

The gene mutation also made the flies bisexual, leading him to name the gene “genderblind.”

“The mutants are completely bisexual, but fertile. It’s the first gene that really specifically affects homosexual behavior without affecting heterosexual behavior,” he said. (Source: Newswise)

Post Traumatic Stress Disorder Causes Reduced Pain Sensitivity

I’m not really sure if this holds much clinical significance, but it is interesting to note anyway… Apparently people who suffer from Post Traumatic Stress Disorder literally feel less physical pain.

“Before fMRI, patients with PTSD already showed a significant reduction in pain sensitivity. During imaging, patients with PTSD rated a fixed temperature as significantly less painful than control veterans.” Patients with PTSD showed altered pain processing in brain areas associated with mood and cognitive pain processing., “the authors added.

While this came as a surprise to me initially, I suppose it could have something to do with them having more cortisol/adrenaline in their system than the average person.

Nightmares Correlated with Five-Fold Increase in Suicide Risk

It’s interesting how sleeping problems seem to be a hallmark of illness. Whether it’s OCD, or on the opposite end of the spectrum, Schizophrenia, at the very least insomnia is correlated with both of these illnesses.

The study, conducted by Nisse Sjöström, RN, and colleagues of Sahlgrenska University Hospital in Göteborg, Sweden, focused on 165 patients between the ages of 18-68, who were admitted to medical units or psychiatric wards at Sahlgrenska after a suicide attempt. It was discovered that 89 percent of subjects reported some kind of sleep disturbance. The most common complaint was difficulties initiating sleep (73 percent), followed by difficulties maintaining sleep (69 percent), nightmares (66 percent) and early morning awakening (58 percent). Nightmares were associated with a five-fold increase in risk for high suicidality.

It seems that nightmares may be clearly indicative to clinicians of certain danger.
