Ancient “Super-Acoustics” technology used on Malta

Researchers detected the presence of a strong double resonance frequency at 70Hz and 114Hz inside a 5,000-years-old mortuary temple on the Mediterranean island of Malta. The Ħal Saflieni Hypogeum is an underground complex created in the Neolithic (New Stone Age) period as a depository for bones and a shrine for ritual use. A chamber known as "The Oracle Room" has a fabled reputation for exceptional sound behavior.

During testing, a deep male voice tuned to these frequencies stimulated a resonance phenomenon throughout the hypogeum, creating bone-chilling effects. It was reported that sounds echoed for up to 8 seconds. Archaeologist Fernando Coimbra said that he felt the sound crossing his body at high speed, leaving a sensation of relaxation. When it was repeated, the sensation returned and he also had the illusion that the sound was reflected from his body to the ancient red ochre paintings on the walls. One can only imagine the experience in antiquity: standing in what must have been somewhat odorous dark and listening to ritual chant while low light flickered over the bones of one’s departed loved ones.

Sound in a Basso/Baritone range of 70 – 130 hz vibrates in a certain way as a natural phenomenon of the environment in the Hypogeum, as it does in Newgrange passage tomb, megalithic cairns and any stone cavity of the right dimensions.  At these resonance frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores vibrational energy.  Echoes bounce off the hard surfaces and compound before they fade.  Laboratory testing indicates that exposure to these particular resonant frequencies can have a physical effect on human brain activity.

What is astounding is that five thousand years ago the builders exploited the phenomenon, intentionally using architectural techniques to boost these "super-acoustics". Glenn Kreisberg, a radio frequency spectrum engineer who was with the research group, observed that in the Hypogeum, "The Oracle Chamber ceiling, especially near its entrance from the outer area, and the elongated inner chamber itself, appears to be intentionally carved into the form of a wave guide."

The same people who created Ħal Saflieni also engineered a complete solar calendar with solstice and equinox sunrise alignments that still function today in one of their above-ground megalithic structures. There is no question that a sophisticated school of architectural, astronomic and audiologic knowledge was already in place a thousand years before the Egyptians started building pyramids.

Brain activity patterns preserve traces of previous cognitive activity

Weizmann Institute scientists discover that spontaneously emerging brain activity patterns preserve traces of previous cognitive activity.

This research suggests a number of future possibilities for exploring the brain. For example, spontaneously emerging brain patterns could be used as a “mapping tool” for unearthing cognitive events from an individual’s recent past.

Or, on a wider scale, each person’s unique spontaneously emerging activity patterns might eventually reveal a sort of personal profile — highlighting each individual’s abilities, shortcomings, biases, learning skills, etc.

Neural ‘synchrony’ may be key to understanding how the human brain perceives

with one comment

Georgia Tech, Back in the News:

Garrett Stanley, a Georgia Tech/Emory University biomedical engineering professor, has published almost 40 articles related to “reading and writing the neural code.” In his latest perspective article, he wrote that the specific timing of electrical pulses may be key to understanding how the human brain perceives what we see, feel and hear.

Despite many remarkable discoveries in the field of neuroscience during the past several decades, researchers have not been able to fully crack the brain’s “neural code.” The neural code details how the brain’s roughly 100 billion neurons turn raw sensory inputs into information we can use to see, hear and feel things in our environment.

In a perspective article published in the journal Nature Neuroscience on Feb. 25, 2013, biomedical engineering professor Garrett Stanley detailed research progress toward “reading and writing the neural code.” This encompasses the ability to observe the spiking activity of neurons in response to outside stimuli and make clear predictions about what is being seen, heard, or felt, and the ability to artificially introduce activity within the brain that enables someone to see, hear, or feel something that is not experienced naturally through sensory organs.

Why Traffic Jams Are Bad for Your Health – WSJ.com

leave a comment »

New public-health studies and laboratory experiments suggest that, at every stage of life, traffic fumes exact a measurable toll on mental capacity, intelligence and emotional stability. “There are more and more scientists trying to find whether and why exposure to traffic exhaust can damage the human brain,” says medical epidemiologist Jiu-Chiuan Chen at the University of Southern California who is analyzing the effects of traffic pollution on the brain health of 7,500 women in 22 states. “The human data are very new.”

So far, the evidence is largely circumstantial but worrisome, researchers say. And no one is certain yet of the consequences for brain biology or behavior. “There is real cause for concern,” says neurochemist Annette Kirshner at the National Institute of Environmental Health Sciences at Research Triangle Park in North Carolina. “But we ought to proceed with caution.”

Biometric Brainwaves, Your Unique Signature

with 2 comments

European scientists are developing security systems that uniquely identify people through the pattern of electrical activity in their brain.

This latest and most unique entry into the field of biometrics was developed by researchers at the Centre for Research and Technology Hellas, Greece. It makes use of the EEG (electroencephalograph) which measures the fluctations in brain activity through electrodes placed on the scalp. It is the voltage difference between different parts of the brain that produces the traces known as EEG, the so-called brainwaves.

Each person has a unique pattern of neural pathway which determines their brain activity. This makes the EEG biometric system hard to forge and therefore desirable for use in high security systems.

A research team from Stanford University has found that injecting the blood of young mice into older mice can cause new neural development and improved memory. Team lead Saul Villeda presented the groups’ findings at this year’s Society for Neuroscience conference.
