title: Natural and manufactured objects activate the fusiform face area.
abstract: Recent fMRI studies indicate that the anterior fusiform gyrus (the fusiform face area, FFA) is specialized for face recognition. However, the analyses used to determine face selectivity have not ruled out the possibility that other object categories produce significant activation in the FFA, relative to baseline. In the current fMRI study, we use a conservative hypothesis testing approach to show that FFA activation is not selective for faces. Rather, the FFA response is almost completely explained by a graded response in which faces produce more activation than either manufactured or natural objects, but those categories produce a statistically greater response than the baseline task. These findings question whether the FFA can be interpreted as a specialized module for face recognition.
