Hi Telmo, My error. The method of displaying the optical signal as given below wouldn't work, because there'd be no sync signals on the optical signal to trigger the playback scan.

Was Dennett right after all ? Hi Telmo, I accidentally sent the previous email before I was done, sorry. Please consider this more complete version of the intended whole: Hi Telmo, Those images in the videoclips, while still remarkable, probably were constructed simply by monitoring sensory MRI signals just as one might from a video camera, and displaying them as a raster pattern, artificially converting the time voltage signal into a timespace signal. Perception of the moving image from a given perspective by the brain might take place in the following way : 1) FIRSTNESS (The eye). The initial operation in processing the raw optical signal is reception of the sensory signal. This is necessarily done by a monad (you or me), because only monads see the world from a given perspective. This is not a visual display, only a complex sensory signal. 2) SECONDNESS (the hippocampus ? the cerebellum? ). The next stage is intelligent processing of the optical signal and into a useable expreswion of the visual image. (From the monadology, we find that each monad (you or me) does not perceive the world directly, but is given such a perception by the supreme monad (the One, or God). This supreme monad contains the ability to intelligently construct the visual image from the optical nerve signal) 3) THIRDNESS (cerebrum ?) Knowing this visual expresson by the individual monad according to its individual perspective. This perspective is somehow coordinated with motor muscles (left/right, etc.), but I question that this is an actual 2D or 3D "display," such as in the videoclips. (The videoclips are another matter as they are artificialy constructed.) If there is an actual or simulated display then we are faced with Dennett's problem: the infinite regress of spectators, spectators of spectator, etc. But if there is no display, we do not need an observer self, and are possibly ending up with Michael Dennett's materialist concept of the self. This might be called epi-phenominalism. The self is simply an expression of the brain. I do not at present know the answer.

Obviously the brain achieves the same result, but I find it hard to believe that it convergts the time signal into a timespace signal using a raster pattern display.

Hi again Roger, It's a bit better than that. A machine learning algorithm is trained to decode neural activation signals. The training is performed by showing the subject known images, and letting the algorithm learn how their neural activity maps to these images. The real magic happens when you show them new stuff, that the algorithm wasn't trained for. To me, the most impressive stuff here is when it fails. If you pay attention to the videos, you will see the algorithm decoding different (but similar images) from what the one being shown to the subject. For example, when faces are shown, different faces are decoded and then start correcting. My speculation is that we are actually seing visual memories conjured by the brain in its pattern matching attempts. My favorite is the ink blot exploding, where you can see the brain anticipating the explosion, so you get to see a visual of the subject imagining a likely future state.

If it's fMRI, you don't see the riginal video clip as an eye would see it, you see an image of brain activity.

My memory is the identity of my 1p and is what my 1p sees. This is perhaps the most serioous problem of comp. Frankly .... I can understand people not convinced that a computer can have a quale associated to the memory, but memory and personal memory does not pose any problem in computers. Then I have explained why they have a quale too. This is not even theoretical anymore. Here's a rather compelling example of visual information in human brains being uploaded into a computer: http://gizmodo.com/5843117/scientists-reconstruct-video-clips-from-brain-activity? -- You received this message because you are subscribed to the Google Groups "Everything List" group.
