Brain-Scanning Tech May Threaten Our Right to Cognitive Liberty

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.

“Toward Narrative Disruptors and Inductors: Mapping the Narrative Comprehension Network and its Persuasive Effects”, DARPA

http://csc.asu.edu/projects/

In 2012, the CSC was awarded by the Defense Advanced Research Projects Agency (DARPA) a $6.1 million dollar research grant to study the neurobiology of narrative comprehension, validate narrative theories and explore the connection between narrative and persuasion.

This groundbreaking research study will employ multi-modal neuroimaging, combining the temporal resolution of EEG with the spatial resolution of fMRI.

The project seeks to validate narrative theories that to date have rested on interpretive approaches, rather than empirical, neurophysiological study.

In so doing, the project aims to discover the neural network(s) involved in narrative comprehension and persuasion, and to come to a further understanding of how elements of existing narrative theories can induce or disrupt narrative understanding by the presence or absence of those structural components of narrative.

Sky Deutschland to broadcast adverts directly into train passengers’ heads

leave a comment »

Sky Deutschland has developed technology to transfer adverts from train windows directly and silently into commuters’ heads.

Passengers leaning their head against the window will “hear” adverts “coming from inside the user’s head”, urging them to download the Sky Go app.

The proposal involves using bone conduction technology, which is used in hearing aids, headphones and Google’s Glass headset, to pass sound to the inner ear via vibrations through the skull.

Passengers leaning their head against the window will “hear” adverts “coming from inside the user’s head”, urging them to download the Sky Go app.

 

A video for the Talking Window campaign released by Sky Deutschland and ad agency BBDO Germany states: “Tired commuters often rest their heads against windows. Suddenly a voice inside their head is talking to them. No one else can hear this message.”

The voice comes from a Sky-branded transmitter made by Audiva that is attached to the train window.

BBDO spokesman Ulf Brychcy told the BBC: “If our customer Sky Deutschland agrees, we will start with the new medium as quickly as possible.

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.

Iranian scientist claims to have invented ‘time machine’ – Telegraph

leave a comment »

Update:  False, possibly State-Sponsored propaganda:   http://www.theatlanticwire.com/global/2013/04/iran-time-machine-scientist/64183/

 

An Iranian businessman claims to have mastered time with a machine that allows users to fast forward up to eight years into the future.

Ali Razeghi, a Tehran scientist has registered “The Aryayek Time Traveling Machine” with the state-run Centre for Strategic Inventions.

The device can predict the future in a print out after taking readings from the touch of a user, he told the Fars state newsagency.

Razaeghi, 27, said the device worked by a set of complex algorithims to “predict five to eight years of the future life of any individual, with 98 percent accuracy”.

As the managing director of Iran’s Centre for Strategic Inventions, Razeghi is a serial inventor with 179 other inventions listed under his own name. “I have been working on this project for the last 10 years,” he said.

“My invention easily fits into the size of a personal computer case and can predict details of the next 5-8 years of the life of its users. It will not take you into the future, it will bring the future to you.”

Razeghi says Iran’s government can predict the possibility of a military confrontation with a foreign country, and forecast the fluctuation in the value of foreign currencies and oil prices by using his new invention.

“Naturally a government that can see five years into the future would be able to prepare itself for challenges that might destabilise it,” he said. “As such we expect to market this invention among states as well as individuals once we reach a mass production stage.”

Razeghi said his latest project has been criticised by friends and relatives for “trying to play God” with ordinary lives and history. “This project is not against our religious values at all. The Americans are trying to make this invention by spending millions of dollars on it where I have already achieved it by a fraction of the cost,” he said. “The reason that we are not launching our prototype at this stage is that the Chinese will steal the idea and produce it in millions overnight.”
