A team of world-leading neuroscientists has developed a powerful technique that allows them to look deep inside a person’s brain and read their intentions before they act.

The research breaks controversial new ground in scientists’ ability to probe people’s minds and eavesdrop on their thoughts, and raises serious ethical issues over how brain-reading technology may be used in the future.

The team used high-resolution brain scans to identify patterns of activity before translating them into meaningful thoughts, revealing what a person planned to do in the near future. It is the first time scientists have succeeded in reading intentions in this way.

“Using the scanner, we could look around the brain for this information and read out something that from the outside there’s no way you could possibly tell is in there. It’s like shining a torch around, looking for writing on a wall,” said John-Dylan Haynes at the Max Planck Institute for Human Cognitive and Brain Sciences in Germany, who led the study with colleagues at University College London and Oxford University.

That doesn’t look like something to get worried about quite yet.  It looks as though they still need to take lots of scans of you beforehand to get an idea of your brain’s individual characteristics, and even then they’ve only got a 70% success rate.

Give them time, though. . .it will be good to have legislation in place so that it’s ready for when it’s needed.

Whatever happened to ‘knock before you enter’ for crying out loud!  This is the second post about mind reading and then talking to people’s brains. 

I don’t know how everyone else feels about all this, but I think it’s getting pretty scary

Science decodes ‘internal voices’

Researchers have demonstrated a striking method to reconstruct words, based on the brain waves of patients thinking of those words.

The technique reported in PLoS Biology relies on gathering electrical signals directly from patients’ brains.

Based on signals from listening patients, a computer model was used to reconstruct the sounds of words that patients were thinking of.

The method may in future help comatose and locked-in patients communicate.

Several approaches have in recent years suggested that scientists are closing in on methods to tap into our very thoughts; the current study achieved its result by implanting electrodes directly into a part of participants’ brains.

In a 2011 study, participants with electrodes in direct brain contact were able to move a cursor on a screen by simply thinking of vowel sounds.

A technique called functional magnetic resonance imaging to track blood flow in the brain has shown promise for identifying which words or ideas someone may be thinking about.

By studying patterns of blood flow related to particular images, Jack Gallant’s group at the University of California Berkeley showed in September that patterns can be used to guess images being thought of - recreating “movies in the mind”.

All in the mind

Now, Brian Pasley of the University of California, Berkeley and a team of colleagues have taken that “stimulus reconstruction” work one step further.

“This is inspired by a lot of Jack’s work,” Dr Pasley said. “One question was… how far can we get in the auditory system by taking a very similar modelling approach?”

The team focused on an area of the brain called the superior temporal gyrus, or STG.

This broad region is not just part of the hearing apparatus but one of the “higher-order” brain regions that help us make linguistic sense of the sounds we hear.

The team monitored the STG brain waves of 15 patients who were undergoing surgery for epilepsy or tumours, while playing audio of a number of different speakers reciting words and sentences.

The trick is disentangling the chaos of electrical signals that the audio brought about in the patients’ STG regions.

To do that, the team employed a computer model that helped map out which parts of the brain were firing at what rate, when different frequencies of sound were played.

With the help of that model, when patients were presented with words to think about, the team was able to guess which word the participants had chosen.

They were even able to reconstruct some of the words, turning the brain waves they saw back into sound on the basis of what the computer model suggested those waves meant.

“There’s a two-pronged nature of this work - one is the basic science of how the brain does things,” said Robert Knight of UC Berkeley, senior author of the study.

“From a prosthetic view, people who have speech disorders… could possibly have a prosthetic device when they can’t speak but they can imagine what they want to say,” Prof Knight explained.

“The patients are giving us this data, so it’d be nice if we gave something back to them eventually.”

The authors caution that the thought-translation idea is still to be vastly improved before such prosthetics become a reality.

But the benefits of such devices could be transformative, said Mindy McCumber, a speech-language pathologist at Florida Hospital in Orlando.

“As a therapist, I can see potential implications for the restoration of communication for a wide range of disorders,” she told BBC News.

“The development of direct neuro-control over virtual or physical devices would revolutionise ‘augmentative and alternative communication’, and improve quality of life immensely for those who suffer from impaired communication skills or means.”

I don’t worry about this for as long as it is not mandated to wear a helmet with electrodes or a mini-fmri in it….

It will be the replacement for the “OV-Chipkaart*”.
In due course.

You simply think were you want to go and everything is registred and taken care of at your bankaccount. If you actually go or not.


* OV-Chipkaart is the blundering automated pay as you fare card for dutch citizens in public transport.

I am reminded of hearing someone who had taken the chip out of their Oyster Card (same thing, for UK transit) and put it into a magical sparkly star wand.

1: Extraordinary claims require extraordinary proof. If it does what it says, you should have no problem with this.
2: What proof will you accept that you are wrong? You ask us to change our mind, but we cannot change yours?
3: It is not our responsability to disprove your claims, but rather your responsability to prove them.
4. Personal testamonials are not proof.

What part of ‘meow’ don’t you understand?

Before you criticize someone, you should walk a mile in their shoes. That way, when you criticize them, you’re a mile away and you have their shoes.
