| pubmed-article:8595181 | pubmed:abstractText | 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 suggest the 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. | lld:pubmed |
