Entrainment
How the brain syncs to another source
State of the brain
The natural state of the brain has its own frequency bands. You can alter these states with external signals. Although these are electrical waves, you can alter them with sound, light, and vibrations. Or with pulsed radio signals. If you offer the brain a signal that is close to the original but with more power, the brain accepts these new rhythms and follows them.
Beat
1. Binaural Beats
Playing two different frequencies on opposite ears creates the perception of a beating pattern whose frequency is the difference between those two present tones. For example, if you play a 200 Hz signal into one ear and a 210 Hz signal into the other, you’ll hear a 10 Hz beat. This third tone isn’t present in the signals themselves but is generated in the superior olivary nucleus, a structure deep in the brainstem, making it something of an illusion.
2. Monaural Beats
The combining of the tones to create the beating effect is often achieved digitally, but not always—it is something string instrument players are very familiar with. When you tune a guitar, for example, it’s common to use a note on one string to get another in tune with it, but when they’re still slightly out of sync you get a pulsing sound that’s the remaining difference between them.
3. Photic Stimulation
Here we turn to light. Photic stimulation goes back to Edgar Adrian’s explorations of alpha waves in 1934, and involves a strobe light flickering at the desired brain wave frequency. The resulting entrainment is known as the ‘photic driving response’.Photic stimulation is used to diagnose conditions like epilepsy, which is an abnormal pattern of brain activity that can start in response to flickering light patterns.
4. Haptic Stimuli
Haptics relate to touch and tactile stimuli, so you might also see it called tactile stimulation. It relates to using vibrations of different frequencies that are picked up through the skin to influence brain rhythms.
Vibrations
What can vibrations do.
Vibrations can be translated to electricity to alter neurons in the brain, not only in the ear but also in the brain itself with mechanisensitive ionchannels. Specific low intensity ultrasound. (Zhihai Qiu 2020) frequencies (300 kHz) are substantially more effective in generating tactile and nociceptive responses in humans compared to high frequencies (900 kHz). The strong effect of ultrasound frequency was observed for all pressures tested, for continuous and pulsed stimuli, and for tactile and nociceptive responses.
This prominent effect may be explained by a mechanical force associated with ultrasound. The effect is not due to heating. Vibrations can make neurons in the somatosensory cortex encode vibration frequency in a similar manner to which soundpitch is encoded in the audiotory cortex.
Radio Entraiment
Radio signal entrainment
The brain can also be tuned to follow a radio signal, a low frequency signal. It can entrain in the same way as it did with sound. The basics of this possibility are founded in experiments the Russians did, during 1st. cold war.
A regular strong pulse in a radio signal, can the brain alter its state. Even if it is hidden in a low frequency radio wave as HAARP produces or one of the other stations that are in use to heat and inspect the ionosphere.

“Man is a Bio-Cosmic Transducer; not only a transmitter, but a receiver; and that somehow his brain waves can lock on and modulate this (the earth’s) field, and this might be the medium for ESP. “
7.8 is the number he used,” replied Beck. “We’ve refined that down to three decimal places.
