Scientists Reconstruct Brains' Visions Into Digital Video In Historic Experiment

Well, I wasn't sure in which forum to post this, but I figured folks here would be interested, as it pertains to digital recordings... just not the type you'd expect.

The recordings in question are images directly from the brain:

Here's what the researchers at UC Berkeley did:
They put test subjects into an MRI and showed them video clips (Hollywood movie trailers), while measuring blood flow through their visual cortex with the MRI. That brain activity was then fed to a computer, which "learned" over many sessions what visual stimuli was associated with particular brain patterns.

Then the computer was loaded with 18 million seconds of random video clips. The video clips were analyzed for potential brain patterns and used as a "palette" in recreating a visual record.

In other words: Brain activity can be recorded, and played back as a video.

The process is in its early stages, and more acurate results will take a massive database of imagery and lots of computing power. But the results are unmistakable. We may be closer to the movie "Brainstorm" than you think...
