Electrodermal activity

So if we go back to 1986, uh, I was with a company called Light Sound Research, and we were looking at how a candle flame changes brain s- brain states.

And we were using GSR, so we were just hearing the beeping noises.

We didn't have EEG.

There was no EEG to get at that point.

So what we discovered, and I'll just kind of tell you the kind of the history of it.

We discovered during biofeedback, we're using GSR machines or galvanic skin response systems that measure skin resistance and temperature and things of this nature.

And we noticed that when somebody sat in front of a candle, because they call this the Jyoti meditation.

So when they're sitting in front of it, they would downregulate their nervous system and they would be relaxed.

And what will happen is this starts to self-regulate the alpha theta rhythm.

And this is the brainwave that in all of our research since even the early 80s, or actually it was until 89 that we got an EEG device that we could actually record brainwaves with.

We were using GSR before that.

But as soon as we started noticing that, that's the brainwave that almost every person that we see in the clinical level anyway, they're lacking.
