But what is important to see here in this example, is that these changes of behavior that we see as perceptions or thinking are involving the entire network - 'the circuitry in which the brain participates'. That is, we see changes of behavior in the face, head, the tail and the body of the dog may even be tense. In other words, the whole network of the structure is involved. We recognise these behaviors as thinking. This is what we see.
Metaphors obscure the doing.
For example, life is a metaphor for behavior, doing. A metaphor is rather like a surface. In constituting the explanation with metaphors, they obscure a process which implies behavior, doing. Its almost as if the metaphor, usually a noun, obscures the doing or action. I've always felt that very strongly.
