Noë claims that "The character of conscious experience can vary even though the neural activity underpinning it does not change.  This is the basic lesson of Sur’s studies. "   (Noë, 2009, p. 54).  So, this is what Noë thinks the experiments show:

But, this is what they really show:

In other words, Noë thinks that Sur's intervention does not change the intrinsic structure of rewired ferret A1, but the intervention does change the intrinsic structure.
