Scientists at the University of California, Berkeley, have reconstructed the internal “movie” that plays in a person’s head. To re-create dynamic visual experiences, they used functional magnetic resonance imaging (fMRI) to measure the brain activity of volunteers (the other members of the research team) as they watched short movie clips (left panel in the video below). A computational model crunched the fMRI data to reproduce the images, as shown in the right panel.
The team, led by Shinji Nishimoto and Jack Gallant, say that the technology is decades away from enabling people to read others’ thoughts and intentions. It could become a powerful tool to communicate with people who cannot verbalize, such as stroke victim and coma patients. This visual image reconstruction study appears in the September 22 Current Biology.
The left clip is a segment of the movie that the subject viewed while in the magnet. The right clip shows the reconstruction of this movie from brain activity measured using fMRI. The reconstruction was obtained using only each subject’s brain activity and a library of 18 million seconds of random YouTube video. (In brief, the algorithm processes each of the 18 million clips through the brain model, and identifies the clips that would have produced brain activity as similar to the measured brain activity as possible. The clips used to fit the model, those used to test the model and those used to reconstruct the stimulus were entirely separate.) Brain activity was sampled every one second, and each one-second section of the viewed movie was reconstructed separately.
Germany’s Merkel shrugs aside new book about communist-era past, says she never hid anything 2013 05 25
Chancellor Angela Merkel has shrugged aside a book that suggests she may have been closer to East Germany’s communist system than previously thought, saying she’s never hidden anything.
The 58-year-old Merkel grew up in East Germany and entered politics as communism crumbled in 1989. It’s long been known that, like many, she joined the communist youth organization. She has said she ...
‘Lack of public debate on immigration caused Stockholm riots’ 2013 05 25
Mishra Mrutyuanjai raises some points that we discussed with Mikael Jalving about in our Red Ice Radio program, in January earlier this year.
Sweden should put its political correctness aside and start an open debate on immigration as it’s the only way to avoid a repeat of the Stockholm riots, Mishra Mrutyuanjai, Swedish Democrats movement member, told RT.
Stockholm is reeling as ...

Stockholm experienced a sixth straight night of riots early Saturday, with cars torched in several immigrant-dominated suburbs, as Britain and the United States warned against travelling to the hotspots.
Nearly a week of unrest, which spread briefly Friday night to the medium-sized city of Oerebro 160 kilometers (100 miles) west of Stockholm, have put Sweden’s reputation as an oasis ...

Sweden could be paying a tough price for its policies on immigrants and multiculturalism. A Stockholm suburb erupted into violence for a few hours, as crowds of angry, masked youths from migrant families burned cars, smashed windows and hurled stones at police officers.
What’s believed to have fueled the riot was the death of a 69-year-old man, allegedly shot by ...
‘They don’t want to integrate’: Fifth night of youth rioting rocks Stockholm 2013 05 25
Youth gang riots in the Swedish capital Stockholm have entered fifth straight night. Hundreds of mostly immigrant teenagers tore through the suburbs, smashing windows and burning cars in the country’s worst outbreak of violence in years.
At least six vehicles were torched throughout the city late on Thursday while the police called for reinforcements from other Swedish cities bracing for further ...
