A multicolored odyssey through the brain

Thanks to Dr. Peter Cummings forwarded my this article from the New York Times about a a new book of images of the brain using the latest in computerized imaging techniques. I was struck by one image in particular:

The above image shows the basic organization of the human visual cortex. The New York Times article states: "Data from a functional M.R.I., obtained in a live human subject, illustrate the basic organization of our primary visual cortex, in which neighboring points in a visual scene are mapped to neighboring points on the brain. Visual stimuli far from the center of the gaze are processed in the areas colored dark blue, while visual stimuli in the center of the gaze are processed in the areas colored purple."

I wonder if there is much overlap with that of this seminal study (posted on my office door):
