Extracting images from he brain
I'm reading the proper journal article at the moment, it's good stuff.
I especially like the idea that they can read dreams and extract images from an artists head before they have set pen to paper. Oooh, imagine making music just by thinking about it! sweeeet.
What would you like to do with this marvellous machine?

I'd go for Madonna having her body shattered by playing her own songs at her at extreme bone shattering volume.

I'll Derren Brown you this evening and extract it from your skull ;)

Between 1 and 50, with two digits...

Just seeing those doodles of me in the gimp mask was disturbing enough...

That needs to be turned into a film
It's far too good to just be left as a dream.

let's be fair, you wouldn't have died though
Judy has pickled herself silly on alcohol so much over the years she's automatically preserved meat,
and there's be enough of her to feed you all for years.

I'm sure there would be a nishe market on the interweb
Could make a lot of money that way ;)

But I think they're talking bollocks. There's a huge leap of faith between the idea that you can read images from the visual cortex (which receives input directly from the retina) and the idea that imagined or dreamed images would be found there too. Nothing in the article suggested they had any proof of that (I haven't read the original paper, but...). More likely is that both visual images and imagined images both feed into the same place in the brain that comprises actual experience (Disclaimer: I'm not talking about a person in the brain). The brain is not a film screen.

I'm going to be boring too and agree
(as I have a little bit of knowledge of this area) and repeat that 'the brain is not a film screen'!

It is partly bollocks,
you'll have a very hard time reconstructing a complex scene, there aree simply too many possibilities *they acknowledge this in the paper(. They have managed to have very simple high contrast images constructed using voxel analysis. They use a ton of trials to do it and the amount of computation is quite mammoth, 'dream veiwing' is still, and probably alway will be, a pipe dream.
I always enjoy the news getting all imaginative with things thy don't really understand. Still, if this kind of technology is pushed, there are many possible uses for it. They already have 'brain controlled' wheelchairs for quadraplegics.

And actually
I'm not convinced that any 'leap of faith' is required for constructing an actual or imagined image using this technique. It would be a very interesting test to perform, and may involve different cortical areas but I can't think off hand why it should produce radically different results...
The images are extremely simple don't forget...

My brain's full of tits and chocolate.
No fancy technology required here.

given the slow temporal resolution of fMRI
because it depends on blood flow it has a refresh rate of around 10 seconds, so the idea of being able to extract live spontaneous visual imagery its pretty unlikely at the moment. Still pretty impressive though.

The analysis is done post hoc
but is still pretty cool.
