That being said, I didn't mean to say a disruption will be easy. Eric Topol has an evangelistic streak, and to his credit, he, like that Dr. Oz, is an accomplished cardiologist. (Head of the Clevelnd Cinic.)

My focus is international medicine, and there is much less regulation there. One problem in the US is a pervasive hypnotic trance that people go into when going through the 'health' care system. But many wake up, and now "alternative" treatments are 40 b$. Big Pharma lawyers are sitting around a table all day, trying to figure out how to quash the 'alternative' movement.

And I must inject here a bit of "psycho-epistemology." I have to invent this word, because we (i believe) pretend we are not smack dab in the middle of our efforts and inquiries. I have been trying to center my awareness in myself as the source of the world. This may seem strange to bring up, but I have been inquiring into certain aspects of the quantum mechanical approach to the nature of consciousness.

Wow - I'm way off track. About your thought to do "neural control for biofeedback." Yes, why not? I have recently (past few days) been wrestling with the following question: "If you could measure the correlates of consciousness itself, what would you do with the signal?" What good would it be? You could promise various psychic powers which have been demonstrated under rigorous scientific conditions: ESP, PK, remote viewing.

But the sages of the world do not like to mix power and spiritual development, So tentatively at least, the scientific investigation of consciousness itself must somehow make people know themselves better, to be more themselves, and not hand them power when they have no wisdom. (or at least putatively so.)

Putting aside that "first cause" inquiry for a moment, your idea of a kind of neural excitation to treat disease is worth considering. On a more restricted level, the diagnostics area is definitely feasible, and it's classical physics, no navel gazing QM required.

In this discussion, I have been quite tentative. As a matter of psycho- epistemology, it is permissable to pose an "open question," without any immedate chance of a resolution. This is to "dwell in the unknown," an uncomfortable place for many humans.

So i invite any thoughts on neural excitation, however tentative. Any working hypothesis is better than none. My main WH is that there is a consciousness which is suppressed by the ordinary mind, and which has the super-normal abilities. j

Have you looked at Prof. Michael Persinger's work on the "God Helmet"?

Also Dr. Stuart Hameroff and Dr. William Tiller.

Alas poor Yorick...

Rather than try to do it electronically why not bodge together something from a tobacco tin with a balloon skin or condom stretched tight over the front and a silicon pipe out the back/side glued into position and a modified earbud type fitting on the other end.

The classic design of of the stethoscope head is hard to beat.

My hunch is that they design it to have a natural mechanical resonance around 2Hz so that it couples well with heartbeats.

The air in such a tin is a long way from 2Hz resonant. If the mechanics were weighted to give 2Hz resonance it would knock out all the audible frequencies

Interesting, I built a speaker years ago using a 3/16" dia magnet, a bobbin for a potcore and a 1-1/2" petri dish. I'm thinking it would work as a heart sound pickup, I would probably mount the magnet more towards the center of the bobbin for more output voltage. Here's a picture.

no, but I will. Thanks. I saw an article by Tiller. It's a weird area of research....
