hermore, same-selectivity patches are not physically connected, implying a "face area" may not even exist.

"These results are very exciting and suggest that the visual cortex contains finer category-selective subdivisions than previously believed," said Brad Duchaine, PhD, of the Institute of Cognitive Neuroscience at University College London, who was not involved in the research.

Senior author David Ress, PhD, associate professor of neuroscience at Brown University and a former research scientist at Stanford, explained: "It's no longer just a monolithic face-selective area. This suggests we need to take a step back and study smaller pieces of the brain first, or in addition to, the whole brain." More studies using this high-resolution technique are needed to properly categorize this region of the brain, he added.

Along with Grill-Spector and Ress, Stanford neuroscience graduate student Rory Sayres contributed to the study. The research was funded by the National Eye Institute and the Whitehall Foundation.

"This has a lot of implications for neuroscientists and psychologists," said Grill-Spector. "First, a new model has to explain how the brain recognizes faces and objects. To understand how the brain attaches meaning to a visual scene, scientists need to study both fine- and large-scale brain activity patterns. Second, it may be that what makes one individual exceptional in recognizing faces and another face blind are fine-scale differences in their brains' functional structure."
