@srikrbha said: Thanks @wjcroft. Let me know your experience @khofstadter on using Greentek saline caps with VR headsets. Once again, thanks for all the help both of you. Hi Srikrbha, I'm sorry, but I have no experience with VR headsets. …

Hello. Thanks William. I only tried the S1 and the S3. My S3 looks different than the one in the OpenBCI shop. I think one of the main differences is that the S3 cap has the cable loom integrated. On the shop picture, the cable loom is seperate …

Thanks! If you end up using SuperCollider for the sound/music part, consider https://github.com/khofstadter/OpenBCI-SuperCollider I will have to look into updating it soon ...

Thanks William. Hi Brainmusicguy. I used the Greentek gel-free cap with the Cyton board. Eyes were closed, body and head were not moving, only fingers on the frame drum. So, I didn't have issues with artefacts. The video of the performance is …

Thanks! I will check the work by Val Brown and email Jeff. Regarding the music, do you see any use of audio driving e.g. with binaural beats or monotone music in NF? Thanks, k

Many thanks William, I can think of two setups: * trainer + trainee; * trainer = trainee (e.g. when you create and use your own software, protocols, etc.) In setup 2, the 'user' is informed about all aspects of the protocol (as she/he d…

When sitting while a session, the impedance usually stayed low until the end, but definitely increased a bit. When laying down, for some reason the impedance at the end was always much higher, not sure why. No overnight recording - I don't think I …

The longest I usually do is around 1 hour, not more.

Thanks, I will try

Sad/happy music is a bit subjective and perhaps while meditation (ideally) you are more in an objective mindset. I guess it's not difficult to meditate for 4 hours if you can do it while walking, cycling even working... it depends how you define m…

thanks! Sounds good.
-
thanks, I will try asap.

... in case anyone is interested in binaural beats, please consider participating in this (no EEG) study: https://bcmi.khofstadter.info/aru-talking-science-series-2020/ // you can skip the video where I am talking, the introduction to the surv…

Thanks. Actually, I have no real idea of how good/bad the Muse signal is. I think I like the idea of OpenBCI more because you have more channels and can choose the electrode locations.

Hi Peter, thanks I will check these asap. Did you ever a meditation for calming the mind, for instance Wim Hofs, or another kind of practise with your Greentek cap and see what is happening to your brainwaves? The last few times I reco…
-
Hi Peter, I think I understand what you mean. I remember some of his books being insightful. I also enjoyed listening to David Lynch, Alan Watts, etc. talking about meditation. I often think it's good to hear how different people interpret the same …

If anyone asks me where to start meditation nowadays, most of the time I point them to this Wim Hof video: Another interesting thing I sometimes mention is that some research e.g. [ https://www.semanticscholar.org/paper/RELEVANT-TO-A-UNIFIED-…

Thanks Peter, does not sound that simple to me :-) After watching 'Wild Wild Country' I think my interest in Osho has faded a bit.
-
Thanks Peter, The first neurofeedback protocol I used with OpenBCI in SuperCollider tried to increase theta waves with non traditional shamanic drumming inspired by the REI methods (Jeff Strong). I haven't managed to analyse the raw data in Matla…
-
great, thanks Peter. I will give it a go next time I have the kit together.
-
Now, I don't listen to music any more at all. It is forbidden for hard core meditators. As a last resort, you could turn to John Cage : 4'33

Hi Peter, this might interest you: Cheers, k

Hi Peter, I am sure it is a good idea to look at gamma (as well as other brainwaves) with a variety for classifications/feature extraction. I believe there is a variety of interesting brain-states that can be achieved with a variety of types of m…
-
Hi Peter, I think the alpha in the music video above mainly went up because of my eyes closed, however, it's one of my favourite tracks so the music could have caused some alpha related flow/trance state of mind - I am not really sure (yet). I g…

// some notes to add to the thread: there is some interesting info on coherence used in nf here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6193115/pdf/fnins-12-00729.pdf and I also liked this 'old' TM video:

quick update: The plan was to sort out the phase coherence code for a presentation last month. Of course, I run out of time, so only managed to use FZ's theta median with a neuro-feedback threshold: when this median was above threshold a synthesi…
-
hi All, many thanks for your replies. I am still digesting as there is a lot to learn. So far, Pete's discussion (https://brain-trainer.com/answers/getting-started/coherence-synchrony/) I found enlightening! Programming wise, it should not be …
-
hello! coherence related programming question: In SuperCollider I have 8 floats going up and down representing theta medians for FZ, PZ, FP1, FP2, F3, F4, P3, P4. With my basic DSP skills I could calculate the difference between the 8 flo…

Thanks Peter. The cap demonstrated in the above videos is the 1st generation of the Greentek Gelfree cap. It's called the S1. I have recently started using the the S3 and hope to get some video demos done for youtube shortly. The price I think is …

Hello Alex, Bill and William, thanks for all your responses. Due to close deadlines I needed to start testing with the current system which cannot do 3D voxel sLoreta acquisition nor real-time coherence measurements. I made the neuro-feedback …
