A recent paper by a team from Princeton University and the Free University of Berlin has shown that taste related words engage the emotional brain more strongly than equivalent literal words. They showed that the brain processes everyday metaphors differently from more literal language, with greater emotional engagement. For example, ‘she smiled at him sweetly” created more activation of the emotion centres of the brain than the expression “she smiled at him kindly”, even though they have equivalent meaning and were understood equally well.

Specifically, Hofstadter discusses how self-reference and formal rules allow systems to develop meanings which ‘emerge’ from the system however meaningless the individual elements of that system. That is, the book describes how thinking emerges from the mechanics of neurons firing, creating a unified sense of self, in the same way that a colony of ants self-organises to produce social behaviours which ‘emerge’ from the acts of individual ants.
