Wow, according to this article, scientists have been able to reconstruct images by monitoring brain activity (or rather, cerebral blood flow).

Quote:Then, when the test subjects were shown a completely new set of images, such as the letters N-E-U-R-O-N, the system was able to reconstruct and display what the test subjects were viewing based solely on their brain activity.
For now, the system is only able to reproduce simple black-and-white images. But Dr. Kang Cheng, a researcher from the RIKEN Brain Science Institute, suggests that improving the measurement accuracy will make it possible to reproduce images in color.
Imagine if you could do away with a DSLR, and just plug a "camera" directly into your brain - capturing whatever you see...
Sounds like something from a television SI-FI program. I suppose it's just a matter of time.
This is an expensive toy to use in humans. You need radiactively (very low level) labeled 2-Deoxy-glucose, emiting positrons. You need a very expensive toy to pick 2 positrons traveling at the same time bu in opposite direction and locate them exactly in the brain. In animals (which I used) you can extract the brain and measure the radiactivity in different parts. We were trying to develop a screen for brain toxicity of different environmental chemicals. The radiactive label had to be created just before use and coupled to the molecule just before injected to patients just before the test, because the radiactivity lasted only a short time. PT scans are very expensive to buy and hugely expensive to operate. For now I would stick with your D 200. You could afford to by a truckload of them for the price of a PET scanner. Pavel
I suspect it would only cheapen my photos to accurately portray what I saw through my eyes. I consider myself an average photographer but a good PhotoShopper. I PhotoShop because I want to show what my mind saw - not my eye. Not what? What? Indeed.
[Edit] Now if this device actually recorded what my mind saw, sign me up. Same response. Now what? What?
