All My Brainwave Entrainment is 40 HZ now

This will be a very incoherent post. My brain is all over the place. So let's go!

(Supporting documents will be listed at the bottom of the page)

1: All My Brainwave Entrainment is 40 HZ now. I have been reading about evidence that 40 HZ is the frequency that seems to have some benefit for AD and PD. Apparently with AD and PD (and maybe other neurological diseases) the brain gamma waves weaken and these weak gamma waves actually allow neurodegeneration. Testing finding that boosting the gamma waves is possible. Therefore I am converting all my binaural beats MP3s to 40 HZ (as opposed to the current 10 HZ 40 HZ combo files).

I have posted my first all 40 HZ binaural beats files: Evolution of Symbolism by Helena Blavatsky - https://drive.google.com/drive/folders/1PTsmEtR0MaH4BmcfWCoRJP3osz7vWZQI?usp=share_link

2: I have also discovered there is a LOT more work being done in brainwave entrainment using monaural beats than using binaural beats. Actual trials using 40 HZ monaural sound, lights, and tactile. This is (supposedly) a link to the actual 40 HZ clicking monaural audio MIT used in their trials: https://youtu.be/UVne_84qZkA

Personally, I find that 40 HZ clicking annoying, and as I do have a High School Degree I went ahead and made my own 40 HZ monaural audio files using a 40 HZ sawtooth wave with an audio booked dropped in: Elementary Theosophy - https://drive.google.com/drive/folders/1-JIX5sCXBM_Cz0eHjk9cYATAgsduKhsC?usp=share_link

One thing about monaural beats is you do not have to use headphones (but I usually do use headphones)

3: I have added a 40 HZ flickering light to my arsenal. MIT did a study with 40 HZ flickering light synchronized with that 40 HZ clicking sound on mice and had success. I bought this $60 flickering bulb: https://www.amazon.com/dp/B08X4W6N5M?psc=1&ref=ppx_yo2ov_dt_b_product_details

I can't synchronize my light and sound so I do them separately (I am looking into whether synchronization really matters). I did find this gadget, but don't plan on buying it: Gamma Audio-Visual Stimulation Coupled Audio-Visual Sensory Stimulation C.A.S.S. Entrainment Device $230 https://www.gammalightandsound.com/

You might see some apps and YouTube videos that say they flicker at 40 HZ, but unless your screen refresh rate is (I think) 180 HZ you won't really get 40 HZ.

☐ Optimal flickering light stimulation for entraining gamma waves in the human brain 2021 https://www.nature.com/articles/s41598-021-95550-1

Although light flickering at 40 Hz reduced Alzheimer’s disease (AD) pathologies in mice by entraining gamma waves, it failed to reduce cerebral amyloid burden in a study on six patients with AD or mild cognitive impairment. We investigated the optimal color, intensity, and frequency of the flickering light stimulus for entraining gamma waves in young adults. We compared the event-related synchronization (ERS) values of entrained gamma waves between four different light colors (white, red, green, and blue) in the first experiment and four different luminance intensities in the second experiment. In both experiments, we compared the ERS values of entrained gamma waves between 10 different flickering frequencies from 32 to 50 Hz. We also examined the severity of six adverse effects in both experiments. We compared the propagation of gamma waves in the visual cortex to other brain regions between different luminance intensities and flickering frequencies. We found that red light entrained gamma waves most effectively, followed by white light. Lights of higher luminance intensities (700 and 400 cd/m2) entrained stronger gamma waves than those of lower luminance intensities (100 and 10 cd/m2). Lights flickering at 34–38 Hz entrained stronger and more widely spread beyond the visual cortex than those flickering at 40–50 Hz. Light of 700 cd/m2 resulted in more moderate-to-severe adverse effects than those of other luminance intensities. In humans, 400 cd/m2 white light flickering at 34–38 Hz was most optimal for gamma entrainment.
