Frustrated that you're so narcissistic and stuck inside your head that
no one can really relate to you because, after all, they're not lucky
enough or wise enough or enlightened enough to see the world the way
that you do? Have no fear...science may soon be able to come to your
aid. UC Berkeley bio nerds have succeeded in creating rudimentary images
based on people's brain activity.
Scientists Turn Brain Activity Into Moving Images        UC Berkeley
researchers tap into technology that may one day allow for re-watching
your dreams.There are lots of comparisons to be made: DVR for the brain,
seeing  through someone else's eyes, or a real life version of
"Minority  Report."

But whatever you call it, what researchers at UC Berkeley have done 
with new research could have major implications for getting inside 
someone's head.

Authors of a new study published in Current Biology
<http://www.cell.com/current-biology/abstract/S0960-9822%2811%2900937-7>
were able to reconstruct YouTube videos from a subject's brain
activity  with the help of magnetic resonance imaging. In other words,
study  subjects watched videos while their brains were monitored, and 
scientists were later able to reconstruct approximate images of those 
videos from the brain imaging data.

"This is a major leap toward reconstructing internal imagery,"
coauthor and psychology professor Jack Gallant told ABC News
<http://abcnews.go.com/Health/MindMoodNews/scientists-youtube-videos-min\
d/story?id=14573442> . "We are opening a window into the movies in
our minds."

Subjects watched a variety of images — clips of an airplane, 
elephants walking, text on a screen and Steve Martin in "Inspector 
Clouseau" (really guys? You couldn't have asked for a suggestion
from  the film department on that one?).

Scientists recreated images by mapping tiny changes in blood flow to 
parts of the brain which decode visual images, all while subjects were 
viewing. The results are haunting, ghostly pictures — but
they're also  pretty unfocused. In other words, it's going to be
a long time before  you get brainwave movies in full HD.

Worried it won't be long before the future crimes you've
visualized — or those weird dreams about your 9th  grade social
studies teacher — will go public?  Fear not. As far as 
reconstructing memories for court, the coauthor points out on the 
study's website
<https://sites.google.com/site/gallantlabucb/publications/nishimoto-et-a\
l-2011> : "After all, an accurate read-out of a faulty memory only
provides misleading information."


Gallant also says visual modules exist all over the brain, and that 
researchers will have to build accurate models and mapping capabilities 
before getting further. "We need really big computers," he told
ABC. For  those who wake up wanting to get back to that awesome dream
where they  were flying through a world made of cotton candy and
inhabited by  beautiful people, that may seem like bad news. For others,
it's probably  cause for a sigh of relief.

Here's a video showing some of the original images on the left, and the
composites created from brain activity on the right:
