"The main proposal [...] here is that brain regions responsible for interpreting perceptual input are also those that represent an imagined perception.  For example, the primary visual areas are activated when an object is merely imagined." --from the Sheridan Libraries at Johns Hopkins University:  Davis S. Miall, in "Neuroaesthetics of Literary Reading," in Neuroaesthetics:  Foundations and Frontiers in Aesthetics, Eds., Colin Martindale and Arnold Berleant, Baywood Publishing Company, Inc., 2009, p.241
