Do you have any names of these units @ark?(Ark) I was recently interested in biofeedback machine that is supposed to monitor your brain waves and teach you how to achieve alpha state or delta state. I notice that these machines that were widely available 40 years ago disappeared from the market. Are they so beneficial that they were suppressed?
Q: (Ark) Should we get one?
Q: (Joe) Where do you get them?
(L) Have to find one.
(Ark) Impossible to find. But I'm sure they must exist but just secret. I mean, it's stupid! Now they are selling headsets which are supposed to monitor brain waves communicating with Bluetooth with your smartphone!
I considered the D.A.V.E. which does not monitor your brainwaves, but can through entrainment generate Alpha, Theta, etc brain activity. I think that perhaps with setting the intention, and also perhaps choosing a trigger word (similar to self-hypnosis) you could use the DAVE to create an alpha wave state for example, which you could learn to re-create with intention/trigger? D.A.V.E. uses flashing light(adjustable intensity) and sound to entrain to the desired state, through wired connections (no Bluetooth or WiFi). I even have a program that I can use to create specific entrainments of specific lengths, and have in the past used that in conjunction with listening to/doing the EE program.
Something else occurred to me, while doing a NeurOptimal session one can see which brainwaves are active using the Matrix Mirror. Through practise would it be possible to increase the Alpha, or Theta by visually using the Matric Mirror to provide feedback? It might not be something you have to work at, but it may take time and patience and relaxation. Especially relaxation to achieve alpha or theta or especially delta(sleepy head!)
