Local maxima are defined in MNI152 standard space as implemented in SPM5.
***p < 0.05 at cluster level of the whole brain corrected; activations in the MTL are in bold;
**p < 0.05, cluster level of small volume corrected;
*p < 0.001, uncorrected; ITC, inferior temporal cortex; L, left; R, right; BA, Brodmann area; MNI, Montreal Neurological Institute.
