István Hospital, Department of Neurology, Hungary Background: Processing of facial features involves a network of interconnected visual cortical areas, e.g. the middle fusiform gyrus (fusiform face area, FFA) specialized for processing of invariant facial properties (i.e. identity and gender), and the superior temporal sulcus (STS) responsible for processing of changing facial attributes, such as emotions. Damage to the right inferior temporo-occipital cortex usually leads to impaired recognition of facial identity, i.e. prosopagnosia. We report a case of selective damage to the right fusiform gyrus without prosopagnosia and provide evidence for within-network reorganization of face processing. Methods: A 24yo male patient with history of partial seizures was investigated by structural and functional MRI (fMRI), and psychophysics. fMRI protocol included retinotopic mapping, face vs. object localizers, neutral vs. emotional face tasks, and face/hand inversion tasks. Psychophysics included facial identity, gender discrimination, motion coherence, and orientation discrimination tasks. Results: We found a lesion in the right temporo-basal region involving the fusiform gyrus suggestive of dysembrioplastic neuroepithelial tumor. Psychophysical testing showed no difference in the discrimination of basic visual features (e.g. motion, orientation) between the two hemifields. fMRI revealed intact face processing in the left hemisphere: the FFA and STS were activated during facial identity and emotion matching tasks, respectively. However, in the right hemisphere facial identity processing was associated with the activation of posterior STS. We found no difference in the responses related to visual objects between the hemifields. Conclusions: Our results are consistent with and intra-hemispheric within-network reorganization of invariant facial feature processing from the damaged right fusiform gyrus to the right STS region. The lack of prosopagnosia suggests that this reorganization leads to close to normal face processing. Conference: IBRO International Workshop 2010, Pécs, Hungary, 21 Jan - 23 Jan, 2010.
