Dynamic reorganization of the middle fusiform gyrus: long-term bird expertise predicts decreased face selectivity

What is the functional relationship between face-selective and expertise-predicated object-selective regions in the human middle fusiform gyrus? In two separate fMRI experiments, superior behaviorally-measured bird expertise predicts both higher middle fusiform gyrus selectivity for birds and, concomitantly, lower selectivity for faces. This finding suggests a long-term dynamic reorganization of the neural mechanisms underlying the visual recognition of faces and non-face.
