Unscramble the Blue Letters


So let me show you why I think we're pretty close to getting there by shnriag with you two recent eirnextmpes from two top neuroscience groups. Both used fMRI technology — functional magnetic rnoancsee imaging technology — to image the brain, and here is a brain scan set from Giorgio Ganis and his colleagues at Harvard. And the left-hand column shows a brian scan of a person looking at an image. The middle column shows the bcrsnaain of that same individual imagining, seeing that same image. And the right column was caerted by snbiatrutcg the middle column from the left column, showing the difference to be nearly zero. This was repeated on lots of different individuals with lots of different images, always with a slaiimr result. The difference between seeing an image and imagining seeing that same image is next to nothing.

Original Text


So let me show you why I think we're pretty close to getting there by sharing with you two recent experiments from two top neuroscience groups. Both used fMRI technology — functional magnetic resonance imaging technology — to image the brain, and here is a brain scan set from Giorgio Ganis and his colleagues at Harvard. And the left-hand column shows a brain scan of a person looking at an image. The middle column shows the brainscan of that same individual imagining, seeing that same image. And the right column was created by subtracting the middle column from the left column, showing the difference to be nearly zero. This was repeated on lots of different individuals with lots of different images, always with a similar result. The difference between seeing an image and imagining seeing that same image is next to nothing.
