It is about the reprogramming of the human brain’s electrical activity. This process may or may not work, in any case it remains a pretty interesting theory that will put you on the thoughts.
It is an experiment in the theory stage, in the sense that no such device has been materialized yet.
If we could record the electrical activity of the brain, we will also monitor the process by which it ages and with the brain, the whole body. We can try to record the electrical activity of the brain in the form of electromagnetic waves and invert them (with the help of software), sending them back to the brain.
We need a radio wave transmitter that goes through the brain and is “disturbed” by the brain’s activity, eventually being received by a receiver. The receiver notifies all the changes made to the harmonic radio waves and records the “anomalies”.
This transmitter-receiver system can be placed on the head of the tested person for several months.
The next step is to reverse (through a program) the way the waves propagate, practically from the end to the beginning. Thus we can stimulate the brain (at least in terms of electrical activity) to regenerate and reverse the aging process throughout the body. Basically the brain “fools” the body that it needs to regenerate.
Another hypothesis would be a subject under development, recording the brain activity of the subject and inserting the waves recorded in the brain of a person suffering from a disease who needs his/her cells and tissues (even whole organs) to regenerate.
