Searching for concepts used in Bruce Gerlator's NeuroFocus device
DonEM

TeslaTech posted a YouTube video about exotic research with a conference speaker, Bruce Gerlator, discussing the 'NeuroFocus' (per the video title) device.
The device (circa 2000) is a through-brain current modulated with a randomized mix of frequencies centering near natural brainwave frequencies.
Below is TeslaTech's video demonstrating and discussing the theory of Gerlator's TES device that can be seen by paid membership only, shucky darn.
Any information is helpful!

Don, hi.
There are so many neuro-tech devices and brain related technologies. Your best bet would be to contact the Tesla Tech Conference organizers and ask if they have way to contact Gerlator to get more current information. Since that video was recorded over 20 years ago, it seems likely there have been subsequent developments in the area of that technology. Google searching for Gerlator turns up nothing.

As a couple of other examples, Neurofield manufactures high end equipment for neurofeedback practitioners, that includes various brain stimulation technologies, including tRNS transcranial random noise stimulation, tDCS transcranial DC stim, tACS AC stim, etc. Just checking their site now, I see the brain stim devices are no longer listed as active products. But they do have a second site with more background.

Since the Tesla Tech conferences are no longer active, a better resource may be the Transformative Technology Conferences, which are still ongoing. They have a great Youtube channel with many of the past conference presentations.

OpenBCI devices do not include any brain stimulation technologies. But can be used for neurofeedback and BCI, brain-computer interfaces.

Another good resource is Dr. Cody Rall,

This company appears to be farther ahead than Neurofield, in terms of equipment and options offered. Impressive.

Thank you William!
Your help's like a Rosetta stone for the newbie... all the acronyms for proper searching in meaningful context you gleaned from my post.
