The future is here (witness the bad Philip k dick reference for a title). I often tell student the first remote device is your eyes – but of course unless you’re an artist its hard to convey directly what you see, which is why cameras are so use full. Well now researchers in Berkley have been able to pull data direct from the brian using MRI scanning and convert that back to the image (in this case , pink panther movies!) that the subject was watching.In effect broadcasting what was in the subject’s mind!
Now its clear that the reconstruction realises on a great deal of correlation between the stimulus and the visual cortex blood flow that is being measured in 3-d in effect this couldn’t be done without knowing what was being observed in the first place – buts it’s very very impressive.
If you watch the clip embedded in the article its clear that faces/people here the easiest to reconstruct or maybe we just pull them from the poor quality data more easily
