A recent Electroencephalograph (EEG) study32 recorded N170, a location in the bilateral occipitotemporal cortex that is sensitive to faces, and found that eyes were processed first, then other parts of the face were coded, and finally, face perception occurred after integration of this information.
Electroencephalograph (EEG) did not show epileptiform discharges, but it is not so unreasonable since there are almost 10-20% epileptic patients have normal EEG presentation.
During follow-up her electroencephalograph findings were consistent with encephalopathy showing generalized slow (delta-theta) activity (Figure 2).
