From a number of research studies and experience, it was observed that some ancient archaeological sites of religious significance have a specific affect on brain waves. The resonant frequencies found at these sites were tested on a group of volunteers in the laboratory of the University of Trieste. Audiometric tests conducted at the Otorhinolaryngology Clinic were used and the response was measured using EEG. Similar tests on the same group were repeated at an ancient hypogeum in Italy. Whilst the frequencies were played, we found there was a prevalence of the frontal or occipital (posterior) areas with no particular cerebral hemisphere (left of right) dominating the other. Throughout the experiment some areas of the brain had a split of waves, but only in those volunteers who regularly practiced meditation or prayer. Each volunteer had a different sensitivity to each of the tones played, as each exhibited a strong response to a subjective and personal tone. In the same hypogeum we applied some innovative methods of research to better understand this altered state of mind induced from the vibrations present in the location with very interesting results.
