as well as OXTR and its snp http://www.snpedia.com/index.php/Rs53576 come to mind.

What’s worth noting is that eating a bad diet of white sugar and processed salts reverses this phenomena, causing the nerves to start to close up again. When resuming a clean vegan diet without processed foods the nerve reactivates.
There is no need for a simulation device, just follow the instructions in taoist yoga: alchemy and immortality for a permenant result.

This is because pitch-to-frequency relationships are actually totally arbitrary and have changed a lot over the centuries (specifically, named pitches have steadily risen in frequency). A=440 — the modern western standard that results in E being 41.2 — is really a 20th-century thing (and it’s not universal in India, although based on a quick google, it looks like harmoniums are now mostly sold at A=440).

(The possible 25-100Hz range you mention is a HUGE range in terms of pitch space — a little over two octaves, at A=440 — so, yeah, unless the meditative state really measures right around 40Hz for most people, any individuals who care would need to determine their own meditative-frequency so they can look up the pitch closest to it. And to the extent that a close match matters, people practicing at home then might experiment with a specific-frequency source, such as a good electronic tuner connected to speakers or some purpose-made audio/music, rather than a pitched instrument like a harmonium.)

Just a thought on this one — it would be quite interesting to see if shifting the tone changes the meditative experience. You could even do this quantitatively, I’d think. Would be an interesting experiment. Alternatively if gamma patterns differ by person in their frequency, I wonder if different tones might “resonate” better with different people based on their frequency relative to that person’s gamma frequency (if these are indeed typical of a person rather than varying by occurrence or indeed within occurrence)

Anyway, really neat to run across your site, and I’m greatly enjoying it. Feel free to drop me an email if you feel like it. I’m living down in Philly these days.

If possible, I would like to use it for the cover of a book that I am editing. The book is entitled “Controlled genetic manipulations” and it will be published in Neuromethods series by Springer.

How can I get a permission to use this image?
