Findings indicated that at 110 hz the patterns of activity over the prefrontal cortex abruptly shifted, resulting in a relative deactivation of the language center and a temporary switching from left to right-sided dominance related to emotional processing. People regularly exposed to resonant sound in the frequency of 110 or 111 hz would have been “turning on” an area of the brain that bio-behavioral scientists believe relates to mood, empathy and social behavior.
The ancients in some way could have used this ancient sound technique
for psychological reasons. Not just that but also spiritual reasons as well.
It is said that certain sounds could have certain effects on the brain. And
the ancients probably focused a lot on that through stonehenge.
Sound professors discovered that first parts of the brain and large
areas of the brain began to reonate with a phantom binaural beat.
This frequency is known as frequency following response. Which
balance certain parts of the brain left and right creating something
called hemispheric synchronization. It is said that some adept meditators
have hemispheric synchrony in some parts of their brains.http://www.monroeinstitute.org/wiki/index.php/The_Effects_of_Hemi-Sync_on_Electrocortical_Activityhttp://cellphonesafety.wordpress.com/2006/10/02/how-do-sound-frequencies-affect-the-brain/
