Abstract

NEUROPSYCHOLOGICAL, computational, and psycholinguistic data suggest the existence of semantic maps, i.e. localized representations of semantic information in the brain. Using functional magnetic resonance imaging, this hypothesis was directly tested with a picture naming task involving items from four different semantic categories. Small left lateralized fronto-temporal cortical sites of category-specific activation were found when brain activation signals were averaged. Data suggestthe existence of multiple maps coding high-level representations of objects, such that meaningful distinctions, at least in part, govern the physical distribution of cortical semantic storage.
