From 2016 a group of enthusiasts has been proactively conducting research to record the microwave radiation of the human brain in the UHF/SHF microwave ranges. A unique set of tools that has never been previously used to test human brain is used. As a result, electromagnetic radiation of the human brain has been recorded in the range from 850 MHz to 5.0 GHz with signal power at the level of –130–100 dBm (10–16–10–13 W). The radiation is supposed to have cognitive nature. The registration method is patented (patent RU 2708040 C2). Previous studies have determined the tools, the testing plan and the procedure.

The goal of the new research on June 12–13, 2021 was to confirm the cognitive nature of recorded microwave bursts depending on the “light/dark” stimuli using a new testing plan and the procedure with a significant increase in the number of registrations. Additionally, the search for new tools has been performed.

A total of 166 experiments has been carried out: 140 experiments on a volunteer, 16 on a control sample, 10 background experiments. In each experiment, from 2000 to 5150 values of the amplitude-frequency characteristics of the electromagnetic signal power have been recorded. To process a digital array of data and extract microwave spikes, a specialized software for preliminary statistical analysis have been developed to extract microwave bursts against the background as related to the set threshold and the distribution of the bursts on a frequency scale within the bandwidth. The total number of significant bursts in the dark appeared to be significantly greater than in the light.

The comparison of the electromagnetic signals from the human head and control confirms the hypothesis of the internal source of the radiation that is found to be more intensive in the dark which can signify cognitive nature of the radiation. No significant difference in sensitivity between the R&S HL050 antennas with an external LNA and the domestic P6-222M with a built-in LNA is observed. Thus, the simultaneous tests with 2 P6-222M antennas are possible, which is more.

The obtained results help refine the terms of reference for the development of a real-time multichannel microwave radiometer for spatial mapping of microwave radiation sources and the development of the microwave encephalography technology.
