The one item which he never mentioned, perhaps because he could not accurately determine it, is the power of his transmitter. He published oscillograms prportedly showing variations of the "beats" when his subjects were emotionally aroused or engaged in creative efforts. Later experiments delivered much more startling results: he found that some of his subjects would hallucinate under the influence of high-frequency radio waves, which by then ranged all the way up to 300 Mhz.
In the 1950s and 1960s, Cazzamalli's experiments were carefully duplicated with modern equipment, of much greater sensitivity than his. His "oscillatori telegrafica" (presumably a transmitter as used for wireless telegraphy) was replaced with a very modest low-power oscillator. The reason for this was twofold. In the first place, university authorities take a very dim view of experiments on human beings, even if these subjects are the scientists themselves, volunteering for the part. Second, a previous experiment had indicated in a rather startling way that power was not required to evoke effects in the human nervous system. In fact, there seemed to be some sort of resonant frequency applicable to each individual human.
The experiment was suggested by the behaviour of test animals used in earlier work. These monkeys went through a sequence of behavior which would indicate that something besides thermal effects was operating. To discover if this "something" was subjectively noticeable by an individual, a weak oscillator was swept through the band from 300 to 600 Mhz with the request that the subject indicate any points at which he might notice anything unusual. The subjects were not allowed to see the dial. At a particular frequency, varying between 380 and 500 Mhz for different subjects, they repeatedly indicated a point with almost unbelievable accuracy (as many as 14 out of 15 times).
Subsequent experiments with the same subjects showed that at the "individual" frequency, strange things were felt. Asked to describe the experience, all subjects agreed there was a definite "pulsing" in the brain, ringing in the ears and a desire to put their teeth into the nearest experimenter. The oscillator in this case was putting out only milliwatts of power, and was placed several feet from the subject.
The evidence is that the human organism "radiates" and "reacts to" radio waves of 2.33 meters and its harmonics -- in other words: 129, 258, 387 and 596 mHz.
The Hallucinatory Effects on Humans of Radio Waves
An Italian university professor named Cazzamalli placed human subjects in a shielded room, subjected them to high-frequency radio waves, and claimed to be able to record a "beat" which he received on a simple untuned receiver consisting of a galena crystal, a small capacitor, antenna and sensitive galvanometer. Cazzamalli's experiments took place more than 75 years ago and he did publish early articles on this phenomenon.
