You see a lot of posts about Beta, Alpha and Delta waves, but not so much about the higher end of the brains hz spectrum. Gamma frequencies are 25-100HZ, and have been measured in high levels in meditating Tibetan monks.

I got some interesting effects playing these today:

The first is pretty brutal sounding but does the job:

Gamma wave - Wikipedia, the free encyclopedia

Relation to meditation
Experiments on Tibetan Buddhist monks have shown a correlation between transcendental mental states and gamma waves.[13][14] A suggested explanation is based on the fact that the gamma is intrinsically localized. Neuroscientist Sean O'Nuallain suggests that this very existence of synchronized gamma indicates that something akin to a singularity - or, to be more prosaic, a conscious experience - is occurring.[13] This work adduces experimental and simulated data to show that what meditation masters have in common is the ability to put the brain into a state in which it is maximally sensitive and consumes power at a lower (or even zero) rate, briefly. The "Zero power hypothesis" suggests that the lower power states may correspond to a "selfless" state and the more typical non-zero state, in which gamma is not so prominent, corresponds to a state of empirical self.
As hinted above, gamma waves have been observed in Tibetan Buddhist monks. A 2004 study took eight long-term Tibetan Buddhist practitioners of meditation and, using electrodes, monitored the patterns of electrical activity produced by their brains as they meditated. The researchers compared the brain activity of the monks to a group of novice meditators (the study had these subjects meditate an hour a day for one week prior to empirical observation). In a normal meditative state, both groups were shown to have similar brain activity. However, when the monks were told to generate an objective feeling of compassion during meditation, their brain activity began to fire in a rhythmic, coherent manner, suggesting neuronal structures were firing in harmony. This was observed at a frequency of 25-40Hz, the rhythm of gamma waves. These gamma-band oscillations in the monk’s brain signals were the largest seen in humans (apart from those in states such as seizures). Conversely, these gamma-band oscillations were scant in novice meditators. Though, a number of rhythmic signals did appear to strengthen in beginner meditators with further experience in the exercise, implying that the aptitude for one to produce gamma-band rhythm is trainable.[15]
Such evidence and research in gamma-band oscillations may explain the heightened sense of consciousness, bliss, and intellectual acuity subsequent to meditation. Notably, meditation is known to have a number of health benefits: stress reduction, mood elevation, and increased life expectancy of the mind and its cognitive functions. The Dalai Lama, a bodhisattva and master of Buddhist philosophy, meditates four hours each morning, and he says that it is hard work. He elaborates that if neuroscience can construct a way in which he can reap the psychological and biological rewards of meditation without going through the practice each morning, he would be apt to the innovation. The aforementioned study in which gamma states were induced in mice may be a step in this direction.

Moved to sleep and health.

Gamma waves have been linked to OBE's and lucid dreaming, but move it if you think that's right...

I bow to the might of the moderation department.

**Dark_Merlin** · 07-17-2011 10:39 AM

Hm, from what I'd researched Theta waves were common during sleep/meditation and were used for lucid dreaming/AP. Whenever I use a theta tone it really sorts knocks me out, sending me into deep meditation really quickly. I've never tried Gamma waves before - what effect have they had on you?

I've read that too. It must be true, but we might not know the whole picture. There could be other tones involved.

Theta tones knock me out too. Gamma tones made me alert and relaxed at the same time... They seemed to heighten my senses. Like I'd done 30 minutes meditation.

Maybe a combination might be best.

**Dark_Merlin** · 07-17-2011 10:51 AM

Hm, I've thought about using theta tones to put me to sleep/help me WILD and then use alpha/gamma tones to keep my alertness up in the dream. I haven't tried it yet but I think it'd be an interesting experiment

**Dowzen** · 07-17-2011 10:56 AM

I had exactly the same idea, so it might be worth looking at.

NCH tone generator and Audacity produce tones easily...

**Dark_Merlin** · 07-17-2011 11:22 AM

I downloaded Gnaural and it allows you to generate binaural beats SUPER easily, I dont have the effort to do it but I recommend you give it a shot if you wanna experiment with binaural tones, it's an absolutely fantastic program

**Dowzen** · 07-17-2011 01:04 PM

I'm dloading it now. If you know any other software I'm interested. Welcome to the Gammadrome, BTW. HA!

This one definitely gave me some body rushes and an excited, Christmas Eve type feeling. Shivers, pulse and tingles. I've never got that off a binaural beat before, and I've listened to loads. I found it more effective at near inaudible lower volumes. Higher, it just got irritating.

**zebrah** · 07-17-2011 01:43 PM

I moved it to sleep and health because you didn't mention lucid dreaming once in your op. I am now moving this to lucid aids.

**Dowzen** · 07-18-2011 12:28 PM

The good vibrations from the 40hz wave lasted 20 minutes after listening.

I dloaded Gnaural last night but can't program it well yet. I'd like a 90 minute wav with 10 minutes of 40hz, then 10 of 6 hertz, and so on...

ive read that regular dreaming involves theta but when people go lucid they have short bursts of gamma as their logic centers come online.

Welcome to the Gammadrome zhineTECH!

That makes a hell of a lot of sense to me. Gamma might be responsible for that ZOMG, I'm dreaming realisation.

**zhineTech** · 07-18-2011 03:48 PM

or that ZOMG , I'm dreaming realisation might be responsible for the gamma...

**Dowzen** · 07-19-2011 03:59 AM

zomg you might be right.

Welcome to the Gammadrome saltyseedog. Checking out yr vid now.

Nice, relaxing, bassy + deep. Thx!
