Oh Boy....Your Brain Scans Show Who You're Thinking About

Scientists scanning the human brain can now tell whom a person is thinking of, the first time researchers have been able to identify what people are imagining from imaging technologies.

Work to visualize thought is starting to pile up successes. Recently, scientists have used brain scans to decode imagery directly from the brain, such as what number people have just seen and what memory a person is recalling.

They can now even reconstruct videos of what a person has watched based on their brain activity alone. Cornell University cognitive neuroscientist Nathan Spreng and his colleagues wanted to carry this research one step further by seeing if they could deduce the mental pictures of people that subjects conjure up in their heads.

“We are trying to understand the physical mechanisms that allow us to have an inner world, and a part of that is how we represent other people in our mind,” Spreng says.

Imagining others

His team first gave 19 volunteers descriptions of four imaginary people they were told were real. Each of these characters had different personalities. Half the personalities were agreeable, described as liking to cooperate with others; the other half were less agreeable, depicted as cold and aloof or having similar traits. In addition, half these characters were described as outgoing and sociable extroverts, while the others were less so, depicted as sometimes shy and inhibited. The scientists matched the genders of these characters to each volunteer and gave them popular names like Mike, Chris, Dave or Nick, or Ashley, Sarah, Nicole or Jenny.

The researchers then scanned volunteers’ brains using functional magnetic resonance imaging (fMRI), which measures brain activity by detecting changes in blood flow. During the scans, the investigators asked participants to predict how each of the four fictitious people might behave in a variety of scenarios — for instance, if they were at a bar and someone else spilled a drink, or if they saw a homeless veteran asking for change.

“Humans are social creatures, and the social world is a complex place,” Spreng says. “A key aspect to navigating the social world is how we represent others.”

The scientists discovered that each of the four personalities were linked to unique patterns of brain activity in a part of the organ known as the medial prefrontal cortex. In other words, researchers could tell whom their volunteers were thinking about.

“This is the first study to show that we can decode what people are imagining,” Spreng says.

The medial prefrontal cortex helps people deduce traits about others. These findings suggest this region is also where personality models are encoded, assembled and updated, helping people understand and predict the likely behavior of others and prepare for the future.

“The scope of this is incredible when you think of all the people you meet over the course of your life and are able to remember. Each one probably has its own unique representation in the brain,” Spreng says. “This representation can be modified as we share experiences and learn more about each other, and plays into how we imagine future events with others unfolding.”

I read this the other day, but while the technology itself is advanced....the ability to "see" who you are thinking about is very primitive. haha.

Out of four manufactured "people" they were able to tell mostly who they were thinking about out of those four, but its not like they can just scan your brain and pull up your neighbor's photo. haha.

To me the title sort of over-hyped this....although its possible it may help out finding a criminal out of a police lineup or something. I dunno.

Technology today moves at warp speed. Once they prove the method the refinements are incredibly fast

Yeah, but according to this, they'd actually have to have the original list of people in front of them to be able to compare when they ask you about one of them.

Which is why I was thinking police lineup....

I don't think they could just ask you a question and pull up someone new out of your brain...you know? Like I don't think they could go, "Oh look, RugerGirl is thinking about her Great Grandma Mabel...."

Not saying the technology is an ideal thing, but just saying it doesn't worry me....yet.

Yeah, that's how I read it. If you said "I'm thinking about Great Grandma Mabel" they could take record of your brain activity, and could (supposedly) know the next time you thought about her.

True, I'm sure they could. Although that's a lot of brain scanning and hassle just to find out about Great Grandma Mabel. haha.

I heard a scientist make an interesting claim the other day. At some point they'll be able to download all of the information from your brain and then upload it onto a new brain. Potential for immortality. Where the "new" brain would come from is a possible ethical issue I would think.

Interesting. Maybe you could download when you're 50 and then wipe your brain clean once you have Alzheimers 25 years later and do a reboot with the info from when you were 50..... of course, then you'd lose data, and that could be awkward if you had gotten remarried or something when you were 60....

Does this mean that Arnie could be around forever making bad movies?

And you bring up another ethical concern Is it ethical to force that on generations to come?Tongue I keep picturing Men in Black and the brain eraser wand.
