Fascinating. Three things leap out at me:

  • That is remarkably text-like without actually being text. Makes sense that reading would produce more distinct activity.

  • I would have expected more details on the faces, considering how much processing power is assigned to the task.

  • What's below the elephant is ground, what's above it is sky. Right? It's like the fMRI went "Hey, brain, what color is sky?" "Blue." "And what color is ground?" "Uh, green?"

I would have expected more details on the faces, considering how much processing power is assigned to the task.

The results are obtained by mixing 100 other movies together so it is not surprising that there are no details.

Presumably that's also why some of the clips seem to have jumbled words and letters floating around.
