Medical merriam says this: "a low-voltage occipital wave recorded by electroencephalography during visual activity."

I just found this site: http://www.healingmusic.org/Library/...sciousness.asp

It says: "We are calling brainwave frequency patterns significantly higher than 40 Hz "Hyper-Gamma" brainwave states. More recently, there have been reports by EEG researchers of ecstatic states of consciousness associated with brainwave frequencies of 200 Hz, we are calling these frequencies "Lambda" brainwave states."

Very interesting, do you experience any ecstatic sate?
Yes. Its surprising - quite a good natural high.

I bought the Lambda, Epsilon and PSI CD's directly from Thompson's center for Neuroacoustic Research.

I have only used the Lambda recording so far - about three times. Once with good Bose around ear earphones - and twice on my stereo.

There is a surprising amount of bass in the recordings. I have had the best results by playing the CD on my Stereo loudly and sitting directly between the speakers. My stereo is a very good system - I have 2 paradigm speaker towers that cost 2000$ each and a really good amp and CD player that cost another 2500$. The bass is so amazing on the recordings that it seems to make the whole house buzz and shake.

After about 15-20 minutes of meditating the music and bass swells and you do hit a kind of bliss like state - its very odd. When you finish meditating it takes a while to return to normal. So far I think Lambda is deeply cool.

I ripped the CD for my Ipod also - using Apples "lossless" setting. I read online that you have to use "lossless" for Thompson's work or some of the frequencies are lost - although I suspect this might be BS intended to make people buy the CD's.

I havent tried using Lambda yet in a WILD or DILD attempt. I also havent tried Epsilon yet. Disk 4 of the PSI set is supposedly for LD and AP - I also havent tried this yet.

So far I have had the best results with Theta/Alpha tracks where the binauraul beats are combined with nataural sounds rather than music. I have some of Thompsons's Theta/Alpha recordings of ocean waves, thunder storms, rain, running rivers, etc. These seem to get incorporated into my dreams - with repeated use Im sure they can become an external "dream signs".

I have only been using these recordings for use when sleeping a short time and am still experimenting. So far I have found that Delta is really good at getting me to sleep quickly - and I do seem to dream more if I introduce theta after 4.5 hours.

I mostly use Binuaral Beats for meditating. Normally for 30 minute sessions. I find that I get HH with Theta and gamma after 20 minutes, with Gamma I find also that I reach a state where I forget to breath! I suddenly realise that I havent btaken a breath for a long time and need air quite badly!! I found this disturbing at first but then read on a meditation forum that this is quite a deep trance and quite cool to acheive.

I have plans this weekend for some WILD attempts - and will probably stick to alpha/theta nature sounds for these. I might have some oppotunity to try a DILD from a nap on Sunday or Monday - if so I might try napping to either the LD/AP track from the PSI suite or Lambda.
