I believe the God Helmet works by increasing activity in the temporal lobes.
Research has shown that Hemi-Sync, which is a patented technology of certain binaural beat mixes/layers, increase activity in the temporal lobes as well. Since this is an experimental thread, I can say that I sometimes layer subliminals with a Hemi-Sync mix, exporting it as FLAC with Audacity. I really enjoy the hemispheric synchronization from binaural beats. It has a ton of old research, even on horses.
In essence, the Hemi-Sync mix Focus 10 is three layers of binaural beats: 262/266 175/179 87/88.5.
Sometimes it has variations, one being 100/104, 300/304, 500/504. In essence it is 4 Hz Theta beats on various multiplexed carriers.
Anyway – I also have a device called NeoRhythm. It’s not a God Helmet, but it might be similar. It uses pulsating magnetic fields around the head at various frequencies that can be chosen. Here is the link to that device.
Thank you for your experimental logs, I think they are interesting and important. I don’t journal often, and I don’t encourage experimentation, nor do I share my results from such experimentation. Just a disclaimer.
