Activation to spider vs mushroom pictures in the extrastriate visual cortex. Increased activation in the left fusiform gyrus in phobic subjects was found regardless of perceptual load. Statistical parametric maps are overlaid on a T1 scan (radiological convention: left = right; y = -55). The plot shows the difference of parameter estimates (spider vs mushroom; mean and standard error) for the maximally activated voxel.
