Thread: Published in Nature Neuroscience: 77% induction rate with electrodes on the scalp at 40 Hertz

Re: Binaural beats.

Binaural beats - Wikipedia, the free encyclopedia
Wikipedia refers to the 'cocktail effect' in beat frequencies generally anything over 30 Hz. However in the same article there is reference to a 40 Hz binaural beat frequency.

Perceived human hearing is limited to the range of frequencies from 20 Hz to 20,000 Hz, but the frequencies of human brain waves are below about 40 Hz. To account for this lack of perception, binaural beat frequencies are used. Beat frequencies of 40 Hz have been produced in the brain with binaural sound and measured experimentally.[28]

Ryan Hurd also refers to this in his dreamstudies portal back in early 2011.

i came across this article some days ago:
Gamma-Frequenzen lassen jetzt luzide träumen!

In this blog, Jonathan Dilas (the author) claims he made a MP3 causing gamma waves (based on the above research of course) in the brain leading to lucid dreams. some of his customers says, that they had indeed lucid and vivid dreams.
what to think of this?

some one else who had/have success with gamma sounds?

I'm not an expert yet i belive even if sound was 40 Hz frequency then during travel through earlobe it will become more and more distorted.
Every single person has small yet still differences inside earlobe
So the sound for one person might de-stabilzie and result in 71 Hz from 40 Hz, while for other person it might result in 50 Hz
That's my tiny theory

Hi,
I have tried gamma recordings with no success so far. What I did was this: I made an 8 min, 40 hz simple sine recording using acoustica and and used the iphone app DreamZ that detects REM sleep to deliver the recording. I also tried looping the recording along with 40 min silence for the whole night. Neither method (for several nights) led to any results for me. To make the picture clear, I used to lucid dream a lot but I have many months to try. Hoped for quick results but unfortunately... No success....

I guess there's a slight difference between directly applied 40 hz electricity dose compared to soundwave at frequency of 40 hz
Since the soundwave will more than likely distort itself on the way through your ear canal?

I don't think there is a difference in the perceived frequency. The problem may have to do with brain entrainment. It might be easier to sync the brain waves to a particular frequency using tACS than audio. But again, the original report in Nature Neuroscience that started it all, proved to be -under close investigation- a semi fraud. It did result in statisticaly significant differences in scores but NOT in significant increases in Lucid Dreaming frequency (the 77% was calculated using the completely misleading assumption that anything above mean scores equals a lucid dream...).
So, if the original study did not achieve a significant increase in lucid dream frequency, why should a 40hz audio do that?
So why did I try? Just in case....

The same electrodes monitor for REM and deliver the current as well.
Attached is a clearer picture.

Hi Jeffg.
Can I ask you what exactly do you mean with 70% success rate?
A lucid dream every 7 out of 10 nights/trials?
I mean a real lucid dream at almost every trial - or a "statistically significant change in dream content"....or something...
What was your success rate prior to this setup? Is 70% attributed to the setup or part of it would be your normal accomplishment?
I am just trying to figure out if the cost and the time in developing such a system is justifiable.
If it proves to be, I will most likely build one like yours!
Thanks!
