The lingual gyrus is a structure in the visual cortex that plays an important role in the identification and recognition of words. Studies have implicated the lingual gyrus as being involved in modulating visual stimuli (especially letters) but not whether or not the stimulus was a word. Further, the gyrus is related to the naming of stimuli. Furthermore, the gyrus has shown significant activation when moving from high to low contrast words as well as a correlation between word length and regional activation.
