The visual processing streams that mediate spatial recognition and object identity travel from the primary visual cortex, at the back of the brain, to the prefrontal cortex via dorsal and ventral pathways. In parallel with proposals that these pathways begin to merge within this brain area, Ó Scalaidhe et al. provide further evidence in support of the view that these aspects of visual information, commonly known as "where" and "what," remain largely segregated. They map the locations of neurons in the monkey prefrontal cortex that are responsive to faces, as an exemplar of object identity function, and find them restricted to the inferior convexity, suggesting that the remixing of sensory input and the integration of what and where occurs elsewhere.
