The process, called Decoded Neurofeedback, doesn't require any conscious effort on the part of the subject to overcome their fears, but relies on identifying brain patterns related to a certain fear, which are then 'overwritten' using a reward system. Even better, it looks like the fears are gone for good after treatment, and the researchers say the technique could eventually be used to help treat conditions such as post-traumatic stress disorder (PTSD). "When we induced a mild fear memory in the brain, we were able to develop a fast and accurate method of reading it by using AI algorithms," explains researcher Ben Seymour from the University of Cambridge in the UK. "The challenge then was to find a way to reduce or remove the fear memory, without ever consciously evoking it." Working with 17 volunteers, the scientists first created a 'fear memory' in the participants by associating a certain image with a brief electric shock. brain-scanOne of the brain scans mapped with AI.

Those taking part were told that the reward depended on their brain activity, but it was never explained how. The aim was to gradually associate the AI-identified pattern with a reward rather than something scary, even when the image wasn't consciously brought to mind. "In effect, the features of the memory that were previously tuned to predict the painful shock, were now being reprogrammed to predict something positive instead," says lead researcher Ai Koizumi from the Advanced Telecommunications Research Institute International in Kyoto, Japan. The real test was how the participants would react when shown the original frightening set of images, but when this happened the researchers spotted no signs of fear or enhanced activity in the amygdala – the brain's 'fear centre'. "This meant that we'd been able to reduce the fear memory without the volunteers ever consciously experiencing the fear memory in the process," says Koizumi. That's in stark contrast to the traditional exposure therapy treatment, which involves exposing people with anxiety disorders to the cause of their anxiety in a safe setting. It often works – it's the old idea of 'confronting your fears' to overcome them – but the team behind the new study thinks we can improve on it. Although the sample size in this study was very small, the researchers think their new technique could be developed to create a less stressful way of helping people overcome their fears – which is good news for the 4 to 5 percent of the population with phobias. "To apply this to patients, we need to build a library of the brain information codes for the various things that people might have a pathological fear of, say, spiders," says Seymour. "Then, in principle, patients could have regular sessions of Decoded Neurofeedback to gradually remove the fear response these memories trigger." The findings have been published in Nature Human Behaviour. Post Comment Private Reply Ignore Thread Top • Page Up • Full Thread • Page Down • Bottom/Latest

I question the accuracy of the title, based on the article. It seems what they removed were "phobias" that were artificially created through a short stint in a lab with volunteers. But that may not be the same thing as phobias that people have as a life long conditions, sometimes even without any known historical event that could explain why the phobia exists.
If you can remove phobias,you can also remove mental restraints. Am I the only one that sees the potential danger in this?
That is just a smokescreen. The purpose behind this type of research is to create a populace that "wears red and marches in a straight line" so they cause no problems for the elites that dream of owning the world outright.
Correct. Any application of this would be directed at "homophobia", "islamophobia", etcetera. Socially engineering a Brave New World.
“I am not one of those weak-spirited, sappy Americans who want to be liked by all the people around them. I don’t care if people hate my guts; I assume most of them do. The important question is whether they are in a position to do anything about it. My affections, being concentrated over a few people, are not spread all over Hell in a vile attempt to placate sulky, worthless shits.” - William S Burroughs
