The visual “word form” area, located on the left side of the visual cortex, is like a dictionary. It stores the visual representation of the letters making up thousands of words. The language center is concentrated on the left hemisphere, but research is growing to show the role of the right hemisphere in language processing. Fluency, word retrieval, and correct language production all rely on personal knowledge of semantics, grammar, and vocabulary. Memory is activated within the hippocampus.
