Reconstruction from brain activity
« Online: 30 de Setembro de 2011, 21:25:47 »
A year and a half ago, we published a great feature on the current state of the quest to read the human mind. It included some then in-progress work from Jack Gallant, a neuroscientist at U.C. Berkeley, in which Gallant was attempting to reconstruct a video by reading the brain scans of someone who watched that video--essentially pulling experiences directly from someone's brain. Now, Gallant and his team have published a paper on the subject in the journal Current Biology.

This is the first taste we've gotten of what the study actually produces. Here's a video of the reconstruction in action:

The reconstruction (on the right, obviously) was, according to Gallant, "obtained using only each subject's brain activity and a library of 18 million seconds of random YouTube video that did not include the movies used as stimuli. Brain activity was sampled every one second, and each one-second section of the viewed movie was reconstructed separately."
Don't forget to check out our original feature on this work for some more background into what the researchers would really prefer we call "brain decoding" rather than "mind-reading."

Brandolini's Bullshit Asymmetry Principle: "The amount of effort necessary to refute bullshit is an order of magnitude bigger than to produce it".

Pavlov probably thought about feeding his dogs every time someone rang a bell.
