I am not really sure what he means because the polarity (or magnetic orientation) of a 'permanent magnet' can be reversed if an external magnetic field is strong enough. I think there are a few things wrong with his presentation. The sense that learning is not part of a computational theory of mind is a little far-fetched but then he seems to present play as an unexpected explanation without any mention of the word "learn" (other than in the introduction where he says, "We speak instead about learning more about the connections themselves and about advancing medicine (Van Essen and Ugurbil, 2012 <javascript:void(0);>xVan Essen, D.C. and Ugurbil, K.

It seems like a major oversight.
