On a Different Frequency... Literally?

http://m.huffpost.com/us/entry/7087828

 The above article is about a study that correlates the stimulation of alpha waves to increased creativity, and the scientists are hoping to test further on the effect of stimulating alpha waves on clinical depression. Pretty straightforward, but a couple lines in the article got me thinking.

 Alpha frequency brainwaves oscillate at 8-12 htz, and as the article states, if you are at rest, you are probably in alpha.

The article references previous research that suggests that highly creative people display a lot of alpha waves. This seems plausible, and I wondered... Most of the highly creative people I know either have Asperger's or similar tendencies. It's not uncommon for an Aspie to say they need space or quiet more than most, and we even have an unusual ability to maintain at-rest states WAY longer than NTs. I've been known to read for days on end, and when my friend Starwind gets into a writing streak, you have to hope he notices the sandwich you leave him.

I knew that the brains of Autism spectrum people are different from Neurotypicals (hence the distinction), specifically over-connected in short range and under-connected between regions and hemispheres. But I'd never seen anything related to brainwa

 What I found was the last thing I expected.

A study titled "Resting State EEG Abnormalities in Autism Spectrum Disorders," published in the Journal of Neurodevelopmental Disorders in 2013, describes a common trend in EEG scans of ASD patients regardless of intellectual ability that sharply  deviates from a neurotypical brainwave pattern.

In a Neurotypical at rest, alpha waves are indeed dominant, with beta waves (seen during activity) and theta waves (light sleep or deep meditation) having a little influence, but virtually no delta (dreaming) or gamma waves (hyper-awareness).

An autism spectrum person, however, shows alpha waves with greater power than seen in NTs, yet in the full spectrum alpha waves are the least powerful waves we experience. Theta and beta waves are stronger, while BOTH gamma and delta waves are peaking. It's a complete inversion, the graphs of the two showing a hill and a U shape. But the coherence of all the frequencies is reduced, which is expected with the under-connection between regions.

So this brings up a lot of questions... Like, are the hyper-creative people from the previous research on the spectrum? Do we even know?

I originally thought this was an issue of Aspies spending more time in states other than beta, the primary zone for NTs. That would explain why I'm "just not on the same wavelength" as anyone else, but the actual results are far more bizarre and telling than I expected.
