Two tasks were used to lateralize and localize language functions noninvasively, using functional magnetic resonance (fMRI BOLD sequences). fMRI images produced during comprehension of the gist of a tale derived from an ordered series of inferential questions were used to lateralize and locate the center of and margins within language dominant hemisphere near posterior temporal-parietal-occipital (TPO) cortical area(s), e.g., Wernicke's. A silent noun-generating task was used to lateralize and localize naming functions within and along superior temporal gyrus (STG) and/or the basal temporal language area (BTLA) in fusiform gyrus. Used within a series of tasks, their purpose was to investigate the reliability and validity of replacing the invasive gold standard for language lateralization, Wada test, with a noninvasive test, BOLD fMRI.
