Such depictive areas identified in human brains
Positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) have identified such depictive areas in the human brain.
For the positron emission tomography findings see, for example, Fox et al., 1986, and for the functional magnetic resonance imaging findings see, for example, Sereno, Dale, Reppas, & Kwong, 1995.
