When our attention rests upon a glass of red wine, say, a large number of neurons in different parts of the brain are simultaneously activated. We don’t have a specific ‘glass of wine’ area that lights up, what we have are responses to ‘liquid’, ‘red’, ‘shiny surface’, ‘transparent surface’, and so on. When enough of these are triggered, the brain understands what’s in front of it and constructs the glass of wine for us to ‘see’.
