Subspace? (Part 1 & 1/2)

17 Sep

Donna, who writes for Under Contract to My Wife sometimes, sent me this information a while back.  i’ve been hanging on to it ’cause i knew it would come in handy someday, and today’s the day.

What she sent me comes from the following blog:

The research reference is here:

Here’s what Donna sent me:

How am I going to fit an MRI in the bedroom?

from Pharyngula by PZ Myers

Maybe you’ve seen this before: it’s a diagram of the sensory and motor cortex of the brain, with a little man or homunculus drawn over it to illustrate the somatic areas associated with each region. You see where the little man’s knee is on the left image of the sensory cortex? Stick an electrode in there and zap it, and a patient/victim will feel a sensation in his knee. Put the patient in an MRI and tickle his knee, and that region of the brain will light up. Cool, huh?

{Sorry, the diagram won’t copy onto the blog, you’ll have to go to the original post…}

Another cute feature: look in the medial longitudinal fissure. You see the homunculus’s toes, and right down there, located beyond the toes, is where the genital sensory area is located. Poke at that with an electrode and…we’re talking happy time at the Mad Scientists’ convention. But notice, though, that in the diagram of the homunculus, the poor creature’s genitals are drawn, and they’re male. It’s a bit sexist, don’t you think?

This bias has now been corrected.

a team led by Lars Michels at University Children’s Hospital in Zurich, Switzerland, used functional magnetic resonance imaging to confirm that the position of the clitoris on the homunculus was in approximately the same position as the penis in men. Barry Komisaruk at Rutgers University in Newark, New Jersey, and his colleagues have now used the same method to map the position of the clitoris, vagina and cervix on the sensory cortex as women stimulated themselves.

I read these things, and I think to myself that I really went into the wrong research field. Oh, well.

They also discovered something else.  

Komisaruk also checked what happened when women’s nipples were stimulated, and was surprised to find that in addition to the chest area of the cortex lighting up, the genital area was also activated. “When I tell my male neuroscientist colleagues about this, they say: ‘Wow, that’s an exception to the classical homunculus,’” he says. “But when I tell the women they say: ‘Well, yeah?’” It may help explain why a lot of women claim that nipple stimulation is erotic, he adds.


Big scientific breakthrough, right?  Well, except for all of us who’ve been saying “there’s a direct line from my nipples to my pussy,” all these years.

Does the research make our experience more valid?  Not really, but it’s clearly more persuasive for those who haven’t experienced it.

i think our experiences and descriptions of subspace are equally valid, and i’m loving the comments on the first part of this.  If you haven’t read them yet, go back one post and check it out.  

More on this later…

      I LOVE this stuff.

      Just the other night, I was trying to tell SIr X about this particular piece of research. Only problem was ~ at the time, i was standing with my back against a door, my arms suspended over my head, and nipple clamps in place…

      My brain was not functioning enough to get past, “They did this study… and um, yeah, nipples, there were nipples…” before I gave up.

      laughing… hugs,

    so i had *no* idea you were writing more on subspace…and i wrote a bit of it too –people will think we are in cahoots!!

    i wish i could write more, and have it sound right but right now i’m just in a post-orgasmic fog after Masters surprise visit tonight….*beaming glow*..

    ps i liked this post a lot but have no brain to expound upon it since i’ve been expounded on a weeee bit..*giggle*

      @’Nilla, I’m glad you wrote about it, loved that post!!!

      And after an evening with your Master, I’m amazed you can even type…
