Brain-Scanning Tech May Threaten Our Right to Cognitive Liberty

leave a comment »

A Conversation About Cognitive Liberty
Brain-scanning and the tools that make it possible can actually benefit society, but the potential dangers cannot be ignored. An open conversation needs to be had about cognitive liberty, and it needs to be between legal experts, neuroscientists and, most importantly, the people whose lives will be effected by its successful application.

Mental Privacy
Your thoughts are your own, are they not? Despite what you say or do in public, privately around others, or what information you share online, the thoughts, ideals, and actions contained within your own mind should be yours, and yours alone. However, advances in technology dealing with brain-imaging/brain-scanning, developed in order to study and interpret the human mind, may be encroaching on this way of thinking, and posing the question: is it our right to control our own thoughts and processes?

 
Believing that we should be the ones in control of our minds is known as cognitive liberty, or the right to mental self-determination. Ask just about anyone the question posed above, and most would agree that yes goes without saying. However when asked the same question with regards to their potential benefits in medicine and law, the answer may be different. If a brain scan could prove someone committed a crime, wouldn’t it be in everyone’s best interest to use it?

Abstract

We experimentally confirmed predictions that modulation of the neuronal threshold with electrical fields can speed up, slow down, and even block traveling waves in neocortical slices. The predictions are based on a Wilson-Cowan-type integro-differential equation model of propagating neocortical activity. Wave propagation could be modified quickly and reversibly within targeted regions of the network. To the best of our knowledge, this is the first example of direct modulation of the threshold to control wave propagation in a neural system.

We therefore predicted that we could speed up, slow down, and block propagating neural activity in neocortical slices with the application of electric fields. Furthermore, we predicted that we could affect wave propagation either globally, over the whole slice, or locally, in a specific region of the slice, by changing the geometry of the applied field.

We experimentally confirmed theoretical predictions that threshold modulation can increase or decrease the propagation speed of, and even block, cortical traveling waves. To the best of our knowledge, this is the first example of direct modulation of threshold to control wave propagation in a neural system. Such modulation could be applied rapidly in a locally precise manner. Since neural systems permit direct access to threshold, these findings open avenues to novel neural prosthetic applications including control and containment of seizure propagation.

“The implications are that such directed fields can be used to modulate both pathological activities, such as seizures, and to interact with cognitive rhythms that help regulate a variety of processes in the brain.”

The results indicate that electric fields (ephaptic effects) are capable of mediating propagation of self-regenerating neural waves,” they write. “This novel mechanism coupling cell-by-volume conduction could be involved in other types of propagating neural signals, such as slow-wave sleep, sharp hippocampal waves, theta waves, or seizures.”

If their findings, which are reported in The Journal of Neuroscience, can be expounded in further studies, it could help us to better understand how brain waves are associated with things like memory, epilepsy, and healthy physiology.

Ancient “Super-Acoustics” technology used on Malta

June 16th, 2014 Linda Eneix

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

June 26, 2013

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.
