This is your brain. And now this is your brain on YouTube. By using functional magnetic resonance imaging (fMRI) software, researchers at UC Berkeley created a visual representation of what our brains see when we watch a TV or movie. It works as such: scientists show subjects random clips and measure the corresponding cerebral activity. After the computer “learns” what vids evoke what brain activity, scientists feed 18 million seconds of random YouTube videos into the computer program where it reconstructs a movie representation of neural happenings based on the hundred clips most similar to what it sees. Although the method currently only works with images actually viewed, the future goal is to recreate what people see in their dreams and memories — which could give doctors major insight to the minds of the mentally impaired, stroke victims or those with neurological disorders. Inception in real life isn’t exactly around the corner, but the implications of this new technology are pretty mind-blowing. See for yourself in the video after the break — no totem required.

FaceNiff
Remember Firesheep? Well, the cookie snatching Firefox extension now has a more portable cousin called FaceNiff. This Android app listens in on WiFi networks (even ones encrypted with WEP, WPA, or WPA2) and lets you hop on to the accounts of anyone sharing the wireless connection with you. Right now it works with Facebook, Twitter, YouTube, and Nasza-Klasa (a Polish Facebook clone), but developer Bartosz Ponurkiewicz promises more are coming. You’ll need to be rooted to run FaceNiff — luckily, we had such a device laying around and gave the tap-to-hack app a try. Within 30 seconds it identified the Facebook account we had open on our laptop and had us posting updates from the phone. At least with Firesheep you had to sit down and open up a laptop, now you can hijack Twitter profiles as you stroll by Starbucks and it’ll just look like you’re sending a text message (but you wouldn’t do that… would you?). One more image and a video are after the break.

In the midst of a blog post welcoming us to “the future of video” head of YouTube Salar Kamangar confirms that starting today it will add around 3,000 new movie titles for rental in the US, along with reviews and behind the scenes extras. More details are promised to come in another post later today, but right now the video page appears to have the same list of flicks we’ve seen before so the question of which studios will bite is still up in the air. The rest of the post also mentions the YouTube Next program to push new original content on the site with “much more to come” — consider the week of Google I/O underway.

Update: Now we have the additional details, available on the YouTube Blog and after the break — NBC Universal, Sony Pictures and Warner Bros. are the new studios YouTube is partnering with to add the 3,000 new and catalog releases, doubling the amount previously available. The pricing is $2.99/$3.99 for movies viewable via PC or Google TV (no other device support is mentioned) and the FAQ notes that YouTube supports resolutions up to 4K but “most” of the new additions are sadly in SD, which is up to its partners.

Update 2: The YouTube Movies page is updated now, as seen above.
