Numbers are 32-bit representations sampled at 1-second intervals showing delta, theta, low alpha, high alpha, low beta, high beta, low gamma, and high gamma brainwave activity during an orgasm by joreth. i love science!

I've never been so completely delighted to be your friend. It was an honor and a privilege to have participated. FOR SCIENCE!

I already had a spreadsheet open, and the data was already in nice CSV format...



It's good for us humans in the audience.

*poke* lots of numbers down below with No Graph Yet!

(I like graphs, I does.)

There are, now :-)

I felt that all 8 curves on one graph was messy (too much overlap) so I plotted 8 graphs.

Now we need a comparison against unaroused state to see if we can spot any obvious differences.

And, of course, multiple runs to avoid sample error :-)

Yes, I'd like to see the baseline and post orgasm comparison.

I would also be extremely interested to see the differences, if any, of self-induced orgasm versus 3rd party induced.

Data Dump Part 1
Your wish is my command!

Here's the full data set. The first three numbers in each row correspond to signal strength (0=perfect signal, 200=pure noise, rather unintuitively), followed by two proprietary numbers which Neurosky refers to as "concentration" and "meditation." The way these numbers are generated isn't documented, except that they are a function of the other values.

Next numbers are as described above.

First 30 sec or so are a baseline with joreth reading; then about 15 seconds of baseline with her describig a memory, the 15 sec of her just sitting with her eyes closed. You can see dramatic changes in the generated "concentration" and "meditation" values at each of these.

The numbers after are self-stimulation ramping up to orgasm.

Ready? Here we go!

Do any of these channels pick up neural activity related to intentional muscular contraction? The arm and hand movements of self-stimulation might interfere with your signals. The stimulation could be provided by an experimenter, but for best results I suppose it should be someone who knows the subject well. : )

Generally, we try to have the subject avoid moving. Either another person does the stimulation, or self-stimulation is done with a stationary vibrator. The Neurosky chip is actually pretty good at filtering out noise from movement, but it's far from perfect.

I actually don't have to move for self-stimulation, including not moving my hands.

Re: Data Dump Part 1










Not sure anything useful in the Theta/Delta/Low-Alpha curves, but the others show definite activity!

Re: Data Dump Part 1
Looking at the High Beta (easiest to see there, but also visible on the other curves), I'm guessing the "relax" period was actually later than you though (90s->120s) since that's a very low level (pretty much on all except Delta).

One interesting thing from the High Gamma, in particular... From the numbers, the orgasm started around time 178 and completed at 191. Yet the brain was going mad from around time 128 to 210.

what about comparing someones reaction to a roller coaster or carnival ride next and comparing it to the orgasm feed?

just a thought.

What is the actual sample rate of the machine? If it's just once per second then the machine can't properly measure anything above 30Hz (vague memory from 2 decades ago of Shannon's Limit, or something by Shannon anyway). If, instead, it's sampling at a higher rate and only reporting once a second then the spot values may be more accurate, but we still can't correctly reconstruct curves greater than 30Hz.

Or is the machine doing something totally different? What do those numbers actually mean?

Good questions. I'm really not sure.

The data from the Neurosky chip represent heavily filtered values that don't directly correspond to real-world units but are good values relative to each other. The low sample rate is a bit disappointing. My understanding, which may be wrong, is that it samples at a higher rate internally and performs FFTs for noise reduction and calculation of the mysterious "concentration" and "meditation" values in the raw data stream I posted up there in the comments.

The problem with the "relative to each other" numbers is that we're back down to a 60Hz sample rate for returned data, so any higher frequency trends (above 30Hz) are indistinguishable from noise.

Although this may not be a problem for some mad science; if this could be plotted "real time" and then get the subject to try and get the "10 second curve" to match the orgasm values just based on "correct thoughts" (a rough and ready bio feedback rig), might the subject be able to then orgasm just by thinking? :-)

I like the way you think!
